What I mean is that there isn't any easily accesible debugging tools (that I know off, please tell me!), so maybe integrating previewing in C2 would help solve that problem with breakpoints and watches. And as I said, integrating an IDE purely for coding as an alternative to using events could be used for easier plugin and behaviour creation/debug. Besides, I like IntelliSense :/ and prefer writing code as an alternative to using block events.
Again, this is just something I thought of that might be useful to game dev in C2, but then again I wasn't sure on the difficulty on implementing this kind of feature. I completely understand you limitations in terms of staff and time :) it's nothing major, i just thought C2 was missing something.
