I need an addon more powerful than Folder pane View Switcher
I have so many accounts that sometimes I would like see my accounts grouped by special interests.
Folder pane give me the possibility to have my favorite folders, unread folders, etc in panels
but don't give the possibility to group my accounts in personalyzed ways.
That is : don't give the possibility to define new panels.
Any other addon ?
Best Regards
Merry Christmas
