I wish Foobar had the following Opera like gesture for playlist tabs: a double-click on a free space in the tab zone opens up a new playlist tab.

Also to go back and forward in the playlist window (undo-redo changes) implementing two button gestures will be very cool.

use stroke it!

Perfect tool for me: definable mouse gestures, for each application you have...

It's not perfect. Because you cannot define actions like Left Mouse Button Click->Right Mouse Button Click, or Double Click.

But I set it up and it's working ok. I wish Foobar supported these gestures natively. Once you get used to them they rock.

I still wish "Double Click" -> New Playlist Tab. What about "Playlist/Redo" action for start?

And what exactly would it do?

Oops I realized the undo in Foobar just remembers one action. So a double undo is a redo. I think it is more useful to have a larger buffer for undo.
