   - A toolbar made with New Toolbar docks in a lane along the window's left or right edge when its title bar is dropped on that edge, or with Dock to Left and Dock to Right in the title bar's context menu. Toolbars docked at one edge stack from the top, each with its share of the lane's height, and the lane is as wide as its widest toolbar; a lane too short for its stack wraps it into more columns, up to half the window's width, and past that the toolbars show only their title bars, which the mouse wheel scrolls through when even they do not fit. Dragging the title bar out of the lane, or Float Toolbar, floats it again, and Escape during the drag puts it back. Hiding and renaming keep its place, and the workspace keeps it. New toolbars still start floating. The lanes and the stacking are VectorCraft's own rules (#1759; `window.toolbar.dock`, `window.toolbar.float`; `toolbars_dock_and_float_by_their_commands`, `docked_toolbars_stack_in_lanes_along_the_window_edges`, `a_title_bar_dropped_on_an_edge_docks_the_toolbar`).
