First thing first, I must say: Kudos for excellent work (...and choosing Snowy White for screenshots ).
Now, the only problem on my Kubuntu laptop is that Strawberry don't implement any power options. To be precise, after time defined in OS settings my laptop will go to sleep, although Strawberry is still playing.
Earlier, as a workaround, I could start Strawberry with .desktop file containing:
Exec=bash -c 'inhibit_lock=$(qdbus org.freedesktop.PowerManagement.Inhibit /org/freedesktop/PowerManagement/Inhibit org.freedesktop.PowerManagement.Inhibit.Inhibit "strawberry" "playing") ; /path/Strawberry-0.9.3-Qt5-x86_64.AppImage %U ; qdbus org.freedesktop.PowerManagement.Inhibit /org/freedesktop/PowerManagement/Inhibit org.freedesktop.PowerManagement.Inhibit.UnInhibit $inhibit_lock'
but since v0.9.3 that, for some reason, that will not work, nether for Qt5 nor Qt6 appimage. The same thing is with outdated 0.8.3 deb version. Well, you can imagine how annoying it is.
Anyway, Godspeed and if I may a little advice.
If you plan to get Strawberry viral, you really need to implement that modern album grid view for Collection sidebar as some have been requested it, maybe something like KDE's Elisa. Now, I don't promise to use it, but still, you get the point.
Best of luck.
