Hey there,
I'll address each of these suggestions in the order you posted them.
1. We don't want to provide IP information of players to other players. If you (the owner) need it, it should be in the server logs.
2. Team related things are gamemode specific. ULX remains gamemode neutral. You or someone could make this into a module if you like.

4. At its core, ULX is non-invasive. We already have messages you can use with the advert system, but things like this are a bit invasive. Again, you or someone could make this into a module if you like, but it likely won't be added as a stock ULX feature.
Thanks!
