Firstly, I LOVE UltraSlim, using it as a base for my living room entertainment center (need to get yesterdays updates lol)
Just a few ideas of things i've added to mine that I'd like to see in the main release:
1 - python and scratch tabs: I know its possible to run said apps (is scratch installed? I've not tried scratch actually... mental note, check scratch) through a .sh in the apps folder, but i particularly like them having their own tabs
2 - pygame: I may have just broken it while re configuring my python (PyPy), but i had to install pygame to get it working.
3 - scratch: Personally I prefer python, but my kid likes scratch, and I couldnt find the scratch editor
4 - Config manager: I wrote myself a quick program to edit the es_systems.cfg file, and i'm working on one that can do all the config files. When its done, I can send it you if you like, i just think it would make editing configs alot quicker and cleaner (is gui or command line better for this? mines command line)
But yeh, I love it
Thankyou for making this possible.
