 - **Tooth groups:** Shift+same-arch range = connected (linked dots); Ctrl/⌘+same-arch range = singles (one lab row each); click in connected span → collapse to that single only. `toothSelectionGroups.ts`; prune lab `toothProsthesis` on change.
+- **Lab dispatch UI:** due date end-aligned beside title (`sm:flex-row` + `justify-between`; stacks on mobile). Prosthesis type: stacked below `md`, 50/50 same-row from `md`. Content clinical field = **Notes** (not case comments).
+- **Lab comments:** shared `LabCaseCommentsPanel` (newest-first; sent=`justify-start`, received=`justify-end`; `viewerSide`) across Treatment / Cases / Tasks / share. Use logical `text-start`/`text-end`, not left/right.

 - **Lab dispatch attention:** `LabDispatchAttentionPanel` — unsent lab-dependent details; quick jump to dispatch.
 - **History API:** patient-scoped; non-owners filtered by provider on treatment or appointment; org owners see all.
