1.0.2 — first working release

Switch off the Address Book, Calendar, Tasks and Chat spaces individually. Mail and Settings always stay.

Install: download the .xpi below, then in Thunderbird/Betterbird go to Add-ons and Themes → gear → Install Add-on From File. No signing is needed — Thunderbird does not require signed add-ons on any channel.

Then open Tools → Space Control… to pick your spaces. Nothing is hidden until you switch something off.

Requires Thunderbird or Betterbird 140 ESR (pinned 140.*; the element IDs it hides were read from that version and need re-verifying before the range is widened).

See CHANGELOG.md for what was broken in 1.0.0/1.0.1.
