having a small resolution screen and screen i use to hide and show the sidepanel a lot of time.
idk how this feature i request could be for most people + as a non tech guy idk how hard it could be to implement.
just askin, just in case :
having the possibility to setup a shortcut to hide/show sidepanel into the settings
and or
having an arrow in the left of the "create a newplaylist" button to be more intuitive
as you can see, i am not a gimp guy neither 
i guess you can get the idea tho, bein more intuitive/productive. idk how many people use this fonction
I will ask strawberry to replace clementine on opensuse.
It seems to me to be common sense, its better in every point + clementine do telemetry that you can't disable from the settings
