This plugin is supposed to get the ping of your friends' server and give you the tooltip of it and a quick color indicator to give you an idea at a glance. As far as I know the tooptip is working; every server is giving me a ping of "-ms" so I have no way of really knowing if it is giving me the right ping or just the ping of one of the servers.
Right now it will fetch the ping on domchange, but when and if the plugin gets fully working, I'll change it to update on an interval and to stop when a game is playing to reduce the footprint. It is just for quick testing purposes right now.
If you have any suggestions or concerns let me know.
