Bungie.net | Join Fireteam Button — ThiefZero

For Destiny players, this addon adds a button to the Bungie.net LFG fireteam section. Once you join a fireteam, the button is added to the screen.
Press the button and it adds the correct join code ("/join <fireteam leader's ID>") to your clipboard. You can ALT+TAB back to Destiny and enter it into the chat to directly join.

No more hassle with copy pasting and typing the correct command.
