Glad to see people like this.
So here's versions 0.4 of both FlareGEN and FlashGEN.
Changes include some code improvements - everything's neatly arranged in groups now, slider refreshing is done by a function now and some small cleanup here and there.
Visually the dice icon now gives you some feedback and some unnecessary extra refreshing has been removed.
As for usability you can now Ctrl+C to copy and Ctrl+S to save in both. I'm still undecided on including a save dialog or sequential saving, but I suspect this too will be implemented in the future.
Enjoy.
