dsh-session-topics

The DSH sidebar groups sessions strictly by workspace, and workspace membership is derived from each session's cwd. The practical consequence: every session you open under the same directory piles up in one undifferentiated block. dsh-session-topics adds the missing axis — a display-only layer of topic folders that sits between the workspace and individual sessions.

The sidebar now renders as Workspace → Topic → Sub-topic → Session, with an "Unfiled" bucket catching sessions that belong to no topic. Interaction boundaries are deliberately crisp: dragging a session onto the upper or lower half of another session reorders it (with an insertion guide), dragging it onto a topic title files it in, and dragging it onto the "Unfiled" header removes it. A plus button on each workspace row creates a new topic; hovering a topic row exposes buttons for creating a sub-topic, renaming, and deleting. Each session shows a relative timestamp that refreshes every minute. Right-click on a session lets you rename, fork, archive, or remove it from a topic; right-click on a workspace lets you create a topic, rename, or delete the workspace. Expansion state, topic assignments, and session order all persist across refreshes and restarts.

The plugin is entirely client-side: it injects no host services, writes no local files, registers no model-facing prompts, and costs zero tokens. Topic scope is hard-bounded to its parent workspace — cross-workspace drags are rejected outright — so you can always trace a session back to the project it came from. Ideal for anyone running multiple thematic sessions in DSH and wanting to locate them by topic rather than by directory.
