Ive got a picture of what it might look like. There wil definately be more stuff but this is just a picture i drew/made:

I also think all these controls on the side of the phone can be shown on just one screen. (you may not know what im talking about) And i should've put an options control but i forgot to.
P.S. I dont really know how to script in C yet but im learning. This mod/client-side script would probably've already been made once ill know how to script in C or C++.
