What solution is missing in your selfhosted setup? What do you wish existed?

Just curious; what have you not found a self hosted solution for? What app do you wish you had that doesn't seem to exist?

I ask because I'm very eager to develop something new 😜 I'm working on lots of things, but many if them don't have users yet. After I created OliveTin (which has lots and lots of users), it's hard to stay motivated on new projects of you're not sure if they're going to be used.
