hi fxdjacentyfxd!
Pere's idea isn't just an idea!
There is an app that lets users install programs in one click sort of - UC_NET.
You put all installations you want in a folder called 'XDA_UC' and whatever is in there gets installed when you press 'customize'
I understand what Pere is suggesting is - you make a reg edit or anything to mod this app in such a way that it gives users two options:
a) everything in XDA_UC = will install on device memory when we press 'customize'
b) everything in XDA_UC_CARD = will install on storage card memory when we press 'customize'
I have the OEMs required to cook in the roms, if you want.
If you want to have a look at development threads it's here
Thanks drupad2drupad. I will look at this in free time.
Regards
