wow, i'm away from this thread for a few days and now it's gone wild. great improvements to the newest version. i was going to suggest the 'remember window size' feature, but it seems you already implemented it.
one little bug - if you squeeze the window too much, the drop-down box for the Hotkey jumps over to the far right side of the window - see your Hungarian setup to see what i mean.
if you're still looking for ways to improve this, a 'new button' command would be great. it could bring up a dialog box that would allow the user to enter the hex code of a character directly, then reload the INI to show the new button at the end of the list. it would make it a lot more user friendly
