Changelog

1.0.0 – Notation Copilot is now Scorehand. Same key, same account. If you had the old plugin, install this one, then delete the old NotationCopilot folder from your Plugins folder; your key is picked up automatically.
0.9.0 – New look: a branded chat window, with a first-open screen, result cards you can read at a glance, one-tap answers to questions, and a live view of what the Scorehand is doing and which bars it is working on. After an edit you see a small picture of the changed bars. Works on light and dark MuseScore themes.
0.8.3 – Example requests to tap when the chat is empty (they fill the box; you edit and send). The plugin now tells our server when it is opened (plugin + MuseScore version, with your key; never any score content), so we can help people who get stuck before their first request.
0.8.2 – New free plan wording: a free trial of 100 edits, then 10 free edits every month. The plan line shows “Free trial · 57 of 100 edits left” during the trial.
0.8.1 – Shows your plan and edits left at the top of the chat (click it to open your account page: usage, cancel a subscription). The button when you run out now reads “Upgrade / buy edits” and opens the plans page (Pro, Composer, credit packs).
0.8.0 – Lyrics: ask for lyrics (in any language) and they are written under the notes, one syllable per note, with hyphens, melismas and verse numbers. Drum-kit fix: triplets and fills on drum staves no longer leave bars too long, and every edit is checked bar by bar before it is kept.
0.7.3 – Activate without leaving MuseScore: type the 6-digit code from your activation email into the chat, or click “Resend activation email”. Long, detailed requests get more time.
0.7.2 – First open shows three example requests you can click to fill in the message box (edit the bar numbers, then press Enter).
0.7.1 – Windows fix: the plugin now saves its temporary copy of the score in its own folder, so “Could not export the score” no longer happens on Windows; clearer message if that folder is not writable.
0.7 – Key signature changes (transposing instruments get the right written key), title / composer text, line and page breaks; pitch rewrites keep articulations; “edits left” note with a Buy credits button near the end of the free plan.
0.6.1 – Sends an anonymous “plugin opened” ping (version only, never your score) so we can tell if installs work.
0.6 – Scorehand writes the music itself: melodies, scales, exercises, copy/clear bars, dynamics, hairpins and chord symbols.
0.5 – Arranging: section voicing (close / drop 2), string pads and brass hits, easier parts, bass lines. Free plan raised to 100 edits a month.
0.4.1 – “Buy credits” button when the free plan runs out.
0.4 – Edits are applied in place in the open score; one Ctrl+Z undoes a whole request.
