Few days back I wrote this very simple extension for quake 3. It works with Chrome Browser only.With this extension, you can create a list of your fav q3 servers and connect to them right from browser.
Now, I know there are very cool desktop application that may have more features and all. But this extension is exclusively for quake3 and it just works. I'm hoping to develop it further and few more games as well. So, this extension needs qconnect application to be installed so that extension can understand qconnect protocol.
Give it a shot once.
Install this extension from javascript:nicTemp();
