In 6.0 addon has been changed to extend Group Finder instead of Raid Browser (Raid Browser has been removed by Blizzard).

Addon Features:

Dropdown menu with all available activities for easier and faster filtering. All activities are grouped by type and expansion (when applicable). You can also change current search category using dropdown menu without going back.
Ability to copy leader and applicant character names (useful for checking theirs armory profile)
~~Second search box provides advanced filtering using following syntax (only inumber and leader name search works after Blizzard restricted addons from accessing group name and description):~~
- ~~+word - include word (example: +hell)~~ (this functionality was broken by Blizzard)
- ~~-word - exclude word (example: -foundry)~~ (this functionality was broken by Blizzard)
- ~~?word - possible word (example: ?tank ?heal)~~ (this functionality was broken by Blizzard)
- ~~+leadername~~
- ~~-leadername~~
- ~~word/leader filters can be combined (example: +blast -normal)~~
- ~~inumber - required item level filter (example: i680), doesn't work with word filters~~
Extended tooltip for premades displaying classes and their roles of those currently in raid
Proper premade sorting (by creation time instead of internal ID)
~~Auto refresh premade search every X seconds (configurable in settings)~~ (this functionality was broken by Blizzard)
~~Spam groups filter (boost shops etc)~~ (this functionality was broken by Blizzard)
Ability to fast link relevant raid "Curve" achievement to leader
