What about calling it "GoRecycle" instead of "RecycleGo"?
That way all "Go" commands line up in the list of commands and its much easier to find "Go"-related functionality.
Another thing: The script behaves different for existing tabs/paths in left or right of a dual lister.
If I'm on the left side (has focus) and both sides have a tab with a path with potential to be recycled, it will bring the tab from the left side to the front, focus stays left and will not move over to the right (expected bahviour).
If I'm on the right side (has focus) and both sides have a tab with a path with potential to be recycled, it will choose the tab on the left side and give that focus. The behaviour of the command is not "mirrored", so to say and comes unexpected for this case.
Will somebody fix that? o)
