It’s my first UI addon so don’t be strong 
I have in plans to improve it by adding limits sheet and connecting it to data base.
What is it?
This is a simple admin mod with many useful functions that will allow you to control your Garry’s mod server with any gamemode.
With which gamemodes it works?
With every gamemode.
How it opens?
Type in the chat “%acp”
Do I need to install a ULX for perfect work?
No! It works without ULX libary.
How I add/remove admins and superadmins?
It based on users.txt that you will find in garrysmod/settings/users.txt there you are able to add or remove users from accessing to ACP. It’s easy and safe.

Who can access it?
Users that wrote in the users.txt as admins or superadmins.
Can I add/remove user from admin in the game?
