This is a pretty simple one, might have been requested already:
If you had already saved a preset with a certain name, then when you load it back up, change it a bit, then go to save it, it would be nice if it would put the same name in the field where you would normally type in a name for it.
Right now, when you load one up that was saved previously, then go to save it again, you have to retype the name again.
You could of course click on the file you saved from before to write over it, but what if you don't want to write over that one, or want to call it something a tiny bit different liker Manic Arp 1, Manic Arp 2, etc.?
Not a huge deal, just a convenience sorta thing I guess.
