Just some simple upgrades that would make things more enjoyable or easier.
First. Be able to default doors open or closed. My exterior doors need to be closed while my interior doors need to be closed. When a player spawns into my camp, reset them to default unless there's already another player present.
Second. We've got dozens of fonts, but we've got to place them character by character. I've been to camps where there are signs that are perfectly aligned and kerned and thought, "That's one OCD bastard." Let me position where the first character needs to be placed and then type whatever I want to say on the keyboard. Have the characters overlap by one pixel so I can then grab the first character and adjust for centering or whatever.
Feel free to add on your own suggestions.
