Personally, I don't really use playlist (sidebar), so I always hide it when I open Parole. However, if I close Parole and open it again, the playlist is visible again. It would be useful to remember the visibility state of the sidebar, so if it's hidden when Parole is closed, it would still be hidden the next time Parole is opened.
I vote for that. It is very ugly to clic every time the button to hide the playlist, over and over again. Maybe could be configured on preferences or simply remember the last state. Thank your for your work! ;)
Fixed in master.
Great! Thank you for your work! ;)
