FluuDock

Small and Easy addon I created for the Mists of Pandaria release to ensure my group gets in and out of dungeons as fast as possible.

6 Main Buttons
LFG - Opens dungeonfinder
Accept Role Check - Accepts role checks ^.^
Queue Pop - Joins dungeons once the queue pop window appears
Leave Instance - Leaves dungeonfinder dungeons with 1-click, no minimap curse anymore. Doesn't accidentaly leave your group like most macros do when you hit them twice!
Leave Group - Leaves your party/raid.
Reset Instances - Resets all your dungeons.

3 Small Top Buttons
Lock/Unlock - Switches the addon between being movable and locked in place
Minimize - Minimizes everything except the small top Buttons
Settings - Opens the config (can also get there by writing "/Fluu" in chat), to scale the addon to your liking

Also I'd recommend your group/party leader to create and use a macro to queue much faster
"/click LFDQueueFrameFindGroupButton"
Instantly puts you in queue with your last used settings (settings reset after reloading/relogging),
so your group should still be careful when accepting the first dungeon invites
