dsh-sidenote

When you are deep into a long DSH conversation—writing, researching, tracing code—there will always be a moment where the reply surfaces a phrase you want to interrogate or a passage worth a deeper dive. Starting a fresh session throws away all context; asking in the same thread derails the line of thought you are pursuing. dsh-sidenote resolves that dilemma: it forks a full-history sidebar chat beside the main session, so you can side-question, annotate, and close it without disturbing the main thread at all.

Two core capabilities stand out. First, sidebar chat is a true fork of the entire conversation history, not a compressed summary. The side session enjoys equal capabilities—tool calls, further exploration, even nested forks—and multiple instances can coexist, each independently closable and auto-hidden from the left-hand session list to keep things tidy. Second, text annotation lets you select any span in an assistant message, highlight it with a numbered badge, attach a note (or leave it empty), and accumulate as many annotations as you need. Edit, reorder, or delete them freely, then they ride along with your next message as structured context. You can also pipe the quote and note straight into a sidebar chat input for an instant question.

Who is this for? Researchers running long multi-turn sessions, engineers drafting deep-dive documents, and anyone who frequently needs the main thread to stay intact while side questions get answered on the fly. It is a thin consumer plugin on top of dsh-better-sidebar, install-and-go, with zero changes to main-session behavior.
