Ctrl+F opens an overlay that searches every document's lines, not just
the active one, and jumps to the hit on click. Always-on-top is a
plain window pin, off by default, toggleable in settings.
Signed by a new key (public half embedded in tauri.conf.json, private
half + password live in GitHub secrets). CI now signs release artifacts
and publishes latest.json; the app checks on boot and prompts to
install and restart.
Write plain text, get live results per line. English + Russian, units,
live currency rates with crypto, percents, dates and timezones, bitwise
ops, variables and sheet totals. Tauri 2 + TypeScript engine +
CodeMirror 6; daily backups and a deleted-sheets bin.
Inspired by Numi for macOS (numi.app); built from scratch for Windows.
