Library collections can be extended in a consuming file (inherited modes, per-mode overrides with reset, extra variables; library updates keep overrides). Variables export to the REST JSON shape or CSS custom properties and import back (merged by name, validated by the REST reader, one undo step). Gradient stops and variant properties bind to variables. Also fixes clicking a gradient stop adding a new stop.
Fill, stroke, effect and layout grid rows drag to reorder by their grip (a handle shows over the
row, an insertion line where it lands, the row's label follows the pointer like a dragged layer;
Escape cancels; lists that differ across the selection have nothing to drag). New commands
`fill.move`, `stroke.move` and `grid.move {ids?, from, to}` join `effect.move` (lists bottom first,
one undo step; items keep everything, linked list styles are unlinked).
Variable bindings on list items follow their items when a list is reordered or shrinks:
paint colours bind per paint (`fills/<i>/color`, `strokes/<i>/color`; `fill`/`stroke` stay the
first paint's), so a moved bound paint keeps its variable and its neighbours are never recoloured.
`fill.remove`, `stroke.remove` and `grid.remove` refuse negative indices.
Layout grids get settings in the Design panel (size; count, type, width or height, margin or
offset, gutter; colour) whose numbers bind to number variables (`layoutGrids/<i>/<field>`),
re-applied on variable and mode changes. Instance boolean and text properties bind to boolean and
string variables (`componentProperties/<name>`, from the instance's properties panel), kept across
instance rebuilds, following property renames and dropped on delete, reset and detach.
Inspect names the variable of each paint.
