dsh-scratchpad

When a DSH plugin needs to show or let the user edit a large block of text — a full prompt, a config snippet, diff output — the usual approach is to build yet another overlay with its own quirks and close behaviour. dsh-scratchpad collapses that into a single shared service: any plugin calls the scratchpad client API and gets a floating text surface in the centre of the screen, so the user never has to navigate to a dedicated view or remember per-plugin close rules.

The pad offers two modes. In Read mode the text is not editable; clicking the backdrop or pressing Escape dismisses it, while selecting and copying always work. In Edit mode, Save and Cancel are the only exits — a backdrop click deliberately does not close the pad, guarding against an accidental stray click that would discard half-finished edits. Ctrl/Cmd+Enter saves, Escape closes (discarding edits). Text is capped at 2 MB; there is no persistence and no return value. If onSave throws, the pad stays open and the error surfaces in the footer. One pad per tab: an open call simply replaces whatever the pad currently shows.

The plugin has no UI of its own. Its audience is DSH plugin developers who need to present or edit large text. dsh-granular-prompt uses it for full-text viewing, section replacement, and diff review; dsh-diff-view optionally upgrades diff-mode rendering. If you are building a DSH plugin that requires users to read or write a large block of text, this is the foundation you need.
