The Insert tab's Block Palette button now behaves like the View tab toggles
(UCS Icon, View Cube, Ortho, Properties, File Tabs, Layout Tabs): it stays
highlighted while the block palette panel is open and clears when closed.
The Ribbon gains a show_block_palette flag with a set_block_palette setter,
fed into ToggleState and mapped in is_active_tool for the BLOCKPALETTE tool
id. show_block_palette on the app remains the single source of truth; both
mutation paths now mirror it onto the ribbon:
- BLOCKPALETTE / BLOCKSPALETTE command toggles ribbon state alongside the
panel (src/app/commands/blocks.rs).
- Closing the panel via the dock rail close button clears the ribbon state,
matching how Close(Properties) already syncs (src/app/update/dialog.rs).
The drag preview divided the edge height by the raw panel count on the target
side. Closed panels keep their stack slot, so a hidden panel (e.g. the block
palette tucked away while Properties stays open) split the ghost and the drop
index as if it were rendering — leaving a half-height preview on that edge.
Size slots from the panels actually rendered on the edge instead, via a shared
visibility helper used by both the drop-index math and the ghost/edge-tint
geometry.
The dock drag preview computed slot heights and drop indices from the full
window height, but docked panel columns only span the model viewport, so the
preview overlay and insertion point drifted below the actual dock edge. Use the
current viewport height so the ghost and drop index line up with the panels.
Clicking an editable property value field now selects its entire value instead
of only placing the caret, so typing immediately replaces it. The click is
observed through a global left-press subscription (PropPointerPressed); a focus
sweep reports which widget took focus and PropSyncActive maps it back to the
active property row, then issues a select-all operation only when focus landed
on a different field.
The active row stays highlighted while its text input holds keyboard focus and
clears when focus moves elsewhere.
Creating a block from selected entities now bumps the geometry epoch, so the
block palette's per-update stale check notices the new definition and refreshes
its list in place instead of requiring the user to close and reopen the panel.
drop_index previously mapped a pointer position inside a lone full-height panel
to a top/bottom insertion split, offering an impossible drop. Clamp to the
single slot when the edge holds one panel, and cover the multi-slot mapping with
tests.
Style the dock rail tab by its panel state: the expanded (active) panel's tab
gets a primary-colored highlight and border, and a tab whose panel is being
dragged gets a lighter primary tint, so the user can see which panel owns the
edge at a glance.
Sync projection controls from the active camera, preserve the UCS icon in perspective views, and use visible or selected 3D geometry for orbit pivots. Dense mesh vertex grips remain hidden.
Keep all solid geometry GPU-resident during navigation. Use vertex-rate instancing, compact untextured vertices, vertex-cache ordering, and cached silhouette sources without culling geometry.
Reuse full VPort records during camera and tile synchronization so
navigation cannot replace file-defined display state with defaults.
