 - 2026-11-05: Window › Toolbars › Keep Tools Beside the Canvas, off by default, docks the Tools panel between left-side panels and the canvas instead of at the window's left edge, and the canvas's left edge then also docks a floating Tools panel (`window.toolsBesideCanvas`, #5395). Workspaces keep the setting; workspaces saved without it keep Tools at the window's edge. An optional VectorCraft layout choice; headline numbers unchanged.
 - 2026-11-12: Stencil Bridges in the Cutting Tools add-on (Object › Plug-ins › Cutting Tools): strips of a set width are cut out of the selected art so that every island of a stencil cut from it (the inside of an O, a hole in a shape) stays attached to the sheet, by the shortest crossings first, vertical, horizontal or the shortest among 12 directions 15° apart, with up to 16 bridges per island; type is measured by its glyph outlines and stays type, and the original goes to a hidden layer or is replaced. One undo step (`addon.cutting.bridges`). A VectorCraft addition: headline numbers unchanged.
+- 2026-11-13: Banner Hems and Grommets in the Cutting Tools add-on (Object › Plug-ins › Cutting Tools): on the chosen sides of the selected art's bounds, or of each artboard, a hem line at a set depth inside the edge and grommet marks (a circle with a cross) at a set inset, one at each end of a side and the rest spread evenly at most a set spacing apart, stroked in a chosen swatch; a dialog with Preview, one undo step (`addon.cutting.banner`). A VectorCraft addition: headline numbers unchanged.
 - 2026-11-05: Release Type on a Path joins the Type Tools add-on (Object › Plug-ins › Type Tools): each selected type on a path splits into point type with the same text and attributes, on one straight line starting where its first character sat, and the plain path it was set on, with its exact shape and place in the stacking order and no paint; or keeps only the path or only the text, optionally leaving the original. A dialog with Preview, one undo step (`addon.type.releasePath`, #5532). A VectorCraft addition: headline numbers unchanged.
 - 2026-11-04: New Document: the units chosen in Preset Details now belong to the chosen document, as the pane's options are listed for the selected preset; the chosen card shows them, every other Recent and Saved card keeps the units its document or preset was made in, and the built-in tabs still follow the chosen units, so switching between inches and millimetres no longer restyles every recent template. Scores and estimates unchanged.
 - 2026-11-02: Mouse wheel over a closed font-family field in Character, Properties or Control changes selected text through the family list using saved font filters (excluding search text), one undo step per notch, stopping at the ends (#5253). Scores and estimates unchanged.

+([grommet](https://en.wikipedia.org/wiki/Grommet)). The ranges, defaults and rules below are VectorCraft's own. The banner
+is the bounds of the selected art, or each artboard when `allArtboards` is true (the default when nothing is selected).
+`top`, `right`, `bottom` and `left` (each true by default) choose the sides that get marks. On each chosen side a hem
+line runs the whole length of the edge, `hem` points inside it (0 to 100000, default 72; 0 leaves the hem lines out).
+With `grommets` on (the default), each chosen side gets grommet marks `grommetInset` points inside the edge (0 to
+100000, default 36): one at each end of the side, `grommetInset` from the edges across it, and the rest spread evenly
+between them, as few as keep them at most `spacing` points apart (more than 0 and at most 100000, default 1728, 24 in). A corner that two
+chosen sides share has one grommet. Each grommet mark is a circle `diameter` points wide (0.01 to 1000, default 27) with
+a cross through its center. The marks are stroked `weight` points wide (0.01 to 1000, default 0.3) in the color swatch
+`swatch` (default `"[Registration]"`), with no fill.
+
+Each banner gets one group named "Banner Marks", holding its hem lines (named "Hem") and its grommets (groups named
+"Grommet"), added on top of the current layer and selected, as one undo step. While a clip group, or a group inside one,
+is edited in isolation, the groups go on top of the container that holds the outermost clip group around it. The command
+fails with every side off, with no hem and no grommets, with nothing selected while `allArtboards` is false, when a
+banner has no width or height, when a `hem` above 0 reaches the far edge of the banner (the full height with only one
+of the top and bottom chosen, or the full width with only one of the left and right) or meets the hem on the opposite
+side (half the height or width with both chosen), when a `grommetInset` does the same for the grommets or is more than half
+the length of a chosen side, and when the grommets would be more than 100000. Result:
+`{id, ids, hems, grommets}`: the first group's id, every group's id, and the number of hem lines and grommet marks.

 A VectorCraft addition, not a feature of the reference app, so no area score moves. Object › Plug-ins › Cutting Tools › Weed Box and Lines… (`addon.cutting.weed`) adds a weed box and weeding lines around the selected art for vinyl cutting ([what a weeding border is](https://help.arlon.com/what-is-a-weeding-border)). The rest is VectorCraft's own: the box is a rectangle at a margin around the art, and the lines run across it horizontally, vertically or both ways, by count or by spacing, and stop at the art's outlines or at a gap from them. The box and the lines are straight paths stroked in a chosen swatch ([Registration] by default), in one group named Weeding on top of the current layer, added as one undo step. The art is measured by the outlines a cutter cuts: compound paths by their fill rule, type by its glyph outlines, clip groups by what shows, images by their frames, placed files by the art they show, symbol instances by their art, and blends and other live objects by the art they draw. The dialog has Preview. Tests: `cmd::addons::cutting::weed::tests` in `vectorcraft-engine`, `weed_box_and_lines_previews_cancels_and_runs_on_ok` in `vectorcraft-ui-egui` and `command_sweep`.

+
+A VectorCraft addition, so no area score moves. Object › Plug-ins › Cutting Tools › Banner Hems and Grommets… (`addon.cutting.banner`) marks where a printed banner is hemmed ([hem](https://en.wikipedia.org/wiki/Hem)) and where its grommets go ([grommet](https://en.wikipedia.org/wiki/Grommet)). The rest is VectorCraft's own: the banner is the selected art's bounds or each artboard; each chosen side gets a hem line at a set depth inside its edge (1 in by default) and grommet marks at a set inset (0.5 in), one at each end of the side and the rest spread evenly at most a set spacing apart (24 in), with one grommet at a shared corner. Each grommet mark is a circle with a cross through its center. The marks are stroked in a chosen swatch ([Registration] by default), in one group named Banner Marks per banner on top of the current layer, added as one undo step. The dialog has Preview.

 ## Path Precision Tools add-on: Divide into Dashes (2026-11-01)
 
 A VectorCraft addition, not a feature of the reference app, so no area score moves. Object › Plug-ins › Path Precision Tools › Divide into Dashes… cuts the selected paths into separate open paths along the curve (arc length, not straight distance): each `dash` long (0.01 to 1000000 pt, 10 by default) with `gap` between them (0 by default: the pieces touch); the gap pieces are left out unless Remove Gaps is off. With direct-selected segments (or anchors) only those runs are divided, the pattern running on across segments that follow one another, and the rest of such a path stays as pieces of its own. Fit to Corners and Ends gives every run between corners and ends a whole number of dashes, all stretched or squeezed alike so it starts and ends on a dash (a closed path without corners holds whole periods); otherwise the lengths are exact and each run's last piece is what is left. Every piece keeps the path's appearance and is selected; one undo step; at most 100000 pieces (more is refused). The dialog takes lengths in any unit and previews on the canvas. Tests: `dashes::tests` in `vectorcraft-pathops` (exact and fitted lengths, curves measured along them, picked segments on open and closed paths, the piece cap and bad patterns), `divide_into_dashes_*` in `cmd::addons::pathtools::tests` in `vectorcraft-engine` (gaps removed or kept, fitted lengths, the stroke kept, one undo step, selected segments only, bad params and too many pieces refused), `divide_into_dashes_opens_its_dialog_previews_and_runs_on_ok` in `vectorcraft-ui-egui` and `command_sweep`.
