it happens alot when you see such servers:
.:Freddies_roundhouse:. **(PHX wire PCmod) **
My idea was a sort of addon to Gmod itself to see what addons are installed on a server. in a nutshell:
When you right click a server, you can select: Server Addons and it shows what addons are installed to the server.
This is to prevent unexpected big ass amounts of downloads…
And maybe a filter. so if you are looking for a server with the Combine Mech. that it filters out all servers with that addon.
(As i can understand, it may fail to retrieve the names from the Addons folder to the game, so maybe the server owner itself can make a list if its not possible)
