Cool! Looks nice.
There's few things you should fix though:
Although many people have nowdays 1024*786(not sure about those numbers, but you get the point) display, there's also people who still has 800*600-displa ys. Problem is that, when I started AGIStudio at the first time, it started 'below' visiable area, luckily I found the edge of it and managed to drag it from it's hide. Make it start from center or make it maximize itself at start.
Add Utils-thingie is nice too. I clicked Insert the separator-box and then OK. When I tried to edit (double-click at it) it gave me this:
List index out of bounds(0)
And one more thing, please change to background colour of help files back to original yellow. The contrast was lower that way and was easier to read.
