One of your planned features is as follows

• Easy-mode programmer block that ‘compiles’ code onto a floppy disk

And I was just curious if someone made this already and googled up CCEDU.
Have you seen CCEDU? It's mostly exactly what you describe.

If you feel like making your own that's fine but I just wanted to point it out if you felt like the feature was missing from the market.

This got me thinking tho, would be cool with a program like this but made in computercraft instead of a custom GUI

Yeah, that's exactly what I was planning.
