Palettes suddenly disappeared
I'm using MuseScore since a very long time and yes there where problems and you had to know a LOT of work arounds to make it perfectly useful for complex projects. And let me say: I think you are doing a great job and I'm very excited to work with the new version, it all reads amazing.
BUT: just after the update to the newest version, my palettes are suddenly empty. In short: that sucks. Doesn't really matter how that happened, may not have been the update. PLEASE make sure that this stuff doesn't happen. I really don't care how great the new features sound, just make sure you're not ending up in a position, where the overall program becomes less useful.
I like working with MuseScore, I really hope this doesn't change or I end up sticking with an outdated version to make sure everything is working.
I'm in the lucky position, that I have multiple macs, so I'll be investigating this behaviour as soon as I have time. Lets end this with a kind feature request: add an option to save the palette settings :)
