Hey, Zep, I know there's a built-in OS, but I think it would be cool if people cool make their own to use and share like carts.

But what would be great is if you could put in code that will allow you to run cart from the carts from the forum like the default OS

Appreciated if you at least read this post

I second this. It would be great if people could make their own graphical Pico shells.

Right now you can call most of the command-line functions from Lua -- but some of them (e.g. dir() ) just pipe their output directly to print(). It would be better if they sent the output to a string table so you could actually create a shell on top of the command line-- like a mini GEOS.
