So far, we're basically discussing new fonts/translations and the possibility of porting to other architectures. (notably ARM) (just want to recap so I don't miss something or re-suggest)
There are a few usability features that I think would be easy/beneficial to add:
-Appbrowser recursively searches all deps from the tce restore directory, as defined by the boot code (installs any already downloaded deps of a repo-retrieved tcz from the tce dir) (not sure if this is implemented yet, so if it is, please speak up)
-Addition of the tcz-unload custom script (by helander) as a built-in command. Admittedly, this could be done easily enough with remastering, or even just with filetool.lst, but I suggest it be added as soon as possible officially & permanently. This shouldn't be added to Appbrowser/Appaudit due to some inherent issues if, for instance, one removes a dep of a program that they open later.
