If you use Gnome, this is what I use: https://maniacx.github.io/Battery-Health-Charging/ You find it also in the extensions. It is really great.
Ah, thanks. Let me correct it.
Ableton Not sure if it helps, but there is Wine support for Ableton Live: https://appdb.winehq.org/objectManager.php?sClass=application&iId=2113
I guess there is currently no such option.
From my perspective those things are also pretty political. E.g. Ubuntu ditched Flatpak in favor of their Snap solution. Snap has, compared to Flatpak only Ubuntu's proprietary store, where Ubuntu has full control over it. So it's also a fight about influence.
And it's breaking with traditional standards which people got used to and, as it's quite new, smaller things need still to be ironed out.
I have a Librem 5 with Gnome Mobile (Post Market OS) at home and I use it from time. There are still some gaps in the SW here and there, but Gnome is definitely on the right track.
And yes, well supported, decent hardware would be also not unimportant.
All in all, it's not little effort and things would move faster if there was more investment of companies…
Yes, looks indeed expensive :-(
