 ### Fixed
 
+- **PR #2331** by @Michaelyklam (closes #2310) — Live compact Activity rows now show transient user-readable progress such as "Searching workspace", "Reading files", "Updating files", or "Running command" while a long tool-only turn is still working. The label is derived from the current tool category, uses the existing non-persistent Activity summary/duration slot, and does not add synthetic assistant content to the transcript.
+
 - **PR #2315** by @Michaelyklam (closes #2305, refs #749) — WebUI profile creation now seeds bundled profile skills for newly-created non-cloned profiles, matching the CLI's `hermes profile create` behaviour. Pre-fix, creating a profile via Settings → New Profile (without checking "Clone from active profile") left the profile's `skills/` directory empty, which was inconsistent with CLI-created profiles that get the full bundled-skills overlay. The fix calls `seed_profile_skills(profile_path, quiet=True)` after `profile_path.mkdir()` when `clone_from is None`. Cloned profiles still inherit skills from their source — they don't get a second bundled-skills overlay. Seed failures (e.g. `hermes_cli` unavailable in Docker fallback) are logged as warnings, not fatal — profile creation still succeeds.
 
 - **PR #2317** by @Michaelyklam (refs #2312 follow-up #2) — Appearance boot reconciliation now treats explicit `light`, `dark`, and `system` localStorage theme values as user selections when a prior Settings autosave failed. Pre-fix, the predicate `lsHasExplicitTheme = lsTheme === 'system'` only treated 'system' as explicit, so a user who picked `light` on a server defaulted to `dark` (or vice versa) with a failed autosave still reverted to the server default on refresh. Now broadened to `['system','light','dark'].includes(lsTheme)`. Skin handling was already correct (`lsSkin !== 'default'`). Closes follow-up item #2 from the v0.51.66 review (#2312).
