Oh goodness yes please make a full feature editor for FFV. I really want to make an FFV hack after my FF Postlude project and it would be incredibly helpful to have something akin to Pinkpuff's ff4kster. Please take it into consideration at least! 
Making an editor is not my thing. It require a ton of work, but mostly a good interface that the user will easily use to create things. When I create any program I have a vision about it. It doesnt mean sharp detailed image, rather idea how things work as a whole, a common concept, which then I implement and make it vivid image.
TBH I tried even forced myself to get at least something (even couple of times). Alas, nothing.
Regardless I'm willing to do it for you guys, BUT I will do it only if you have a vision for it AND your full support - sharing specific ideas how to do it, suggestions, testing, active in a thread, ...I just noted how "busted" the old status is; it drains stats every 5 ticks, so between two turns you go from normal to totally useless: -18 everything per turn if you had 30 AGL, ouch
Hehe, yes usually on the second turn you start to feel the 'damage' Old has done :D
