I gave this a quick test and it has some nice features - very powerful scanning engine that can search all subdirectories in a given path or assign.
I did find it changed the Workbench colours when starting and left them changed when exiting. Although I'd imagine this is more of a boot time launcher.
Also, it desperately requires a method to jump quickly to letters of the alphabet - by either using left and right to jump to A then B then C etc or sorting games by letter. The long list takes a long time to navigate.
Also seems to take quite a bit of memory. It is however alpha and its nice to see it moving along.
Anyway, always nice to see free projects like this and appreciate the work.
