Potplayer, add bookmarks detach playlist

Hello!

Having moved from kmplayer to potplayer i'm still missing some of it's old options.
I've seen bookmarks being advertised and mentioned for potplayer but i can't find or add them anywhere in the menus. How does it work?
Also i have some skins with detachable playlist. Is there a hotkey to do this for other skins or is it skin based?
