RAIDSNAPSHOT
RaidSnapshot allows you to save snapshots of the raid setup and to restore
them at a later time to its original group setup and raid assistants.
It's useful in PvP battlegrounds, where you can save a snapshot prior to
entering and restoring it upon entering the battleground.
FEATURES
===========================
* Take snapshots of the raid setup (group layout and assistants)
* Restore the snapshot after the raid has changed (e.g. in the battlegrounds)
* Name your snapshots for easy switching between PvP/PvE tactics
* Snapshots are saved when you log out
(Note: previous version 2.0.2 has a bug and doesn't work)
Later versions will have auto create/restore snapshots in battlegrounds. Copy and rename snapshots. And more.
If you have any suggestions, please let me know.
