Use player's Steam ID for RustSuggestion
Would be cool if the avatar could show  steam avatar or a link to an image/icon from the server website.

thanks for all your efforts in building this plugin! 
I'm confused, could you explain a little more on what your suggestion is?
BetterChat already shows players avatar in chat ?
avatar/chat icon is showing the default Rust icon... https://imgur.com/n6UV51y

a cool little feature would be to allow plugin users to change the icon, and use either steamdID icon or a link to a cdn (e.g. Imgur)

"Server Chat" plugin (see below) allows the admin to use the steamID icon as the admin chat icon
