Type in a state, and press enter to mark it. Press enter again to mark another. This was a very quick tool whipped up because why not. Horribly coded, so don't look inside. Just type in a U.S. state name, and it will mark the state. This can be easily changed to mark other locations, just replace the backdrop and hitboxes.
If there is a mislabeled state, which there probably is, tell me and I can fix it. @HiddenSword7 for catching Georgia.
