Vertical, title-based window switcher

[Grant Heaslip]

I'm a recent transplant from OS X to Ubuntu, and while I've found the move 
much easier than expected (Ubuntu has matured a *lot* since the last time 
I gave it a go, which was maybe mid-2007), there's one thing that's been 
bugging me:

On OS X I relied pretty heavily on a window switcher called Witch 
(http://manytricks.com/witch/). Basically, it behaves similarly to Alt-Tab 
in Ubuntu and Windows, but gives a vertical list of window titles (the 
screen-shot shows windows organised by application, but I have it set to 
organise them by last used exclusively). The Compiz application switcher 
only shows the title of the currently-selected window, and is based on 
thumbnails of the windows, which I find mostly useless since I'm often 
working with text-only content that isn't particularly identifiable. A 
list of titles would be much better.

Anyone know of something similar to Witch that will play nicely with 
GNOME, Metacity, and Compiz? Thanks!
