Yes, I'm porting my old MameWah design I did in 2003, which is now woefully out of date and looks like it. Eventually I'm going to redo the entire interface since AM seems to give me more to play with.
I think you'd be disappointed in what a designer like myself (I own a company that designs websites and mobile apps) would do with a frontend. It would probably feel too sparse for most. The biggest problem (IMO) I see people do is they try to do too much or be too "cute". They try to cram every last pixel with something to make it visually "impressive". Usually this just adds too much visual noise and overwhelms the interface.
There needs to be a reason for every single thing on the screen, it needs to communicate to the user, and it needs to be instantly obvious what is going on. Design to a grid, use negative space to your advantage (hint, it helps call out the important bits), don't mix fonts.
Be subtle, don't hit people over the head. Take out every image in the interface...is it still enjoyable to use? If not rework it before you add the images back in. Only add effects (graphical or interactive) if they're needed to communicate something necessary to the user. Ditch the ones that are superfluous.
Basically follow this motto: "The design isn't done when there's nothing more to add, it's done when there's nothing more to take away."
