I've decided to try getting back into MC modding, and my current idea is an improved command block editor. Basically, it will be a completely clientside mod that will replace the current (terrible) commandblock GUI

with an improved, more "IDE" like one (multiple lines, auto-close parenthesis, etc).

I plan to make the mod using MinecraftForge and will use the GuiOpenEvent for launching my GUI. Alternatively, I may use reflection to simply modify the current textbox with a custom, more advanced one, but I think I want to add buttons and stuff too.

If anyone wants to throw together concept art, knows of a pre-existing mod similar to this, etc please comment or lmk.

It will be opensource as soon as there's a working prototype.

How is this project going, Giraffe? From what I saw on IRC, you had done some significant work with building a GUI, but eventually went with a Swing GUI instead of something native? Hope it's coming along well.

Decided to switch to a webapp due to a) mc limitations and b) possibility of sharing commands easily, collaboration, etc.

Im currently using the Ace editor and Bootstrap, will post screenshots and more information when I can
