I think the one of the main gripes with my FE is the lack of customisational options, so next release you will be able to:
Change colors,
Change font types,
Change font sizes,
Add event sounds,
Have MP3's play with the screensaver,
Have a different 'no snap available' image for each emu.
Obviously, the fonts/colors thing is present in pretty much all FE's already, but surprisingly VERY few people have actually requested it in mine - maybe they like my colors?

Also, I'm now extracting much more info from MAME -listinfo. This basically means you can filter on much more stuff - like when you get your gun you can just show gun games. CatVer will be supported too (I just have to add filters for each category).
I expect to release this version next week.
For the following release I hope to add:
Resolution Options,
Simple Skin support,
Howards Wrapper support,
Customisable controls (maybe).
I have to say that when I've done these things my FE is pretty much 100% all I ever wanted plus more. But I'm sure I'll think of something to keep me busy
