Bug Fixes
- Extension prefix trailing colon (#154) — Extensions with
prefix: in manifest now activate correctly (fixes quicksheet-dice, quicksheet-envck, quicksheet-leetcode, quicksheet-pihole).
- Extension CSV pollution (#156) — Extension outputs are no longer saved to CSV on autosave. Extension data is stored in an in-memory overlay and excluded from persistence.
Infrastructure
- Linux cross-platform build fix — Windows
.resx and embedded resources no longer leak into Linux builds.
- 60+ extensions in the ecosystem — see docs/extensions.md for the full directory.
