I'm just curious and something that hit me last night. There arn't that many EV Nova editors out there by my count its less than ten, MC, EVONE, EVNEW, Nova Tools, ResEdit (With TMPLs or hexadecimal if your nuts), and then soon there will be my improved version of Theme Maker.
Now I know that most of these are generally good at several key areas and then fall down in others, except nova tools maybe (actually no, it has no support for OS X).
So my question is this, if you could would you have a go at making your own editing program for your own personal use?
