I think it would be nice to have, and although probably difficult, I think I can make some suggestions:
- Add a built in memory manager. For things that have the potential to crash a server, we wouldn't want something like that to brick our phones, right? Simply have a trigger that trips if the memory being used exceeds a certain amount.
- Add the ability to input/output redstone signals, which can be displayed on a status indicator.
- Due to memory limitations, rednet and multiple terminals may not be a good idea. Not everyone has a superphone.
- Support for the HTTP API already existing in ComputerCraft. That way, you don't have to copy/paste your huge code into your phone, or to a notepad. Upload and download your scripts!
