That was some fast debugging! In any case the start up menu seems to work much better now, as in, it works. I changed Cecil to Rydia successfully, but in that it curiously enough will read Rydia's Level Up Chart when she gains a level. But the actor swapping works very well in that regard. You just have to remember that it's looking at that character's original table, but that might be because I changed the class to Caller rather than Dark Knight, perhaps implying that Levels are linked to Job rather than Actor? Class Changes from that menu also work properly. Stat changes, initial exp and TNL are also working great now.
As for other little things. The game is still looking at some stat chart somewhere for initial HP/MP for instance if you change Cecil's HP to 150, per se he'll still start with 200, but it will be 200/150. The same applies to MP. I guess a trick for that might just be to have an instant HP/MP restore when they join your party to right their HP/MP stats.
Level Ups prior to initial Level Ups are all working properly as well, at least for the one I programmed for Cecil as a test.
Also I was going to complain about cycling through numbers, but seeing that you added PgUp/PgDown Home/End functions, I have no room to complain, hehe. It might be a bit taxing with larger numbers (for say giving FuSoYa a real table) but aside from that looks like this tab is working optimally! Well done!

Hah, never noticed that neat little emoticon...esque... thing... ahem! Good choice with the semi-manual entry of numbers, guess I'll try that out then.

2: Oh wow, this ease of control makes things so much easier for the Characters tab. Everything seemed to work great for it, no bugs or crashes that I could see with it.
