I was thinking of a plugin that shows a menu with some information of some cvars chosen, when a player connects to the server and with a simple command, a menu with the information appears.
Example Using Advertisements 2.0 (Updated 2016/03/23):

The panel changes information as soon as the cvar is updated:

Once a player connects to the server, the menu appears showing the cvar settings, and also using the command !info
I hope you understood my English, I used an online translator.
Linear Mode
