It would be nice to see some snaps of peoples front ends, just for ideas. Although, there are tonnes of this already out there.
Maybe this thread can be dual purpose:
IE Snaps of front ends that others have made, plus a run down on the usability and functionality of the various FE programs...
For me, I think I have solidified on AtomicFE, as it seems to actually work well (read: properly) in vista. Also, the layout editor in it is very easy to use (in respect to other FE layout editors).
I am a former MALA supporter, but it doesnt like VISTA so much. (I wont be using VISTA on the MAME machine, but will be setting up the frontend on a VISTA machine, so I need full compat for that)
