Just checking in, I know I haven't said anything about this for a while, but I haven't really done much RNG-ing.
The add minute function worked a treat for ID/SID abuse on a ROM ;)
Also the spacebar feature is good (although ever since you told me you didn't use it, I've been trying it with the mouse more and more, and getting ok results).
Resizing still needs some work, the text on "Update" (IIRC) is still just an ellipsis when I go on it. Not a real problem, just looks a little messy is all.
Other than that I'm out of things to suggest, this thing's good by me ;)
