for a proposed Boing Bag 3
BB3 is already out, so is BB4, if you count the community-driven projects available for download here:
http://lilliput.amiga-projects.net/bbag4.htmOccasionally people have trouble installing them, but that's the nature of Amiga software in general for ya. Many crazy configs, occasionally someone's going to have an issue. Myself and many others run them daily without any trouble. Runs like butter on my A2000!
There's even updates beyond this, things like Peter K's icon.library that's updated every month or so. Definitely worth a look on Aminet for updates to many of the "core" OS files!
