Blizz Shop to LFoR

ShopToLFOR (Blizzard Store to Looking For Other Raids)
replaces the Blizzard Store MicroButton with a Looking For Other Raids MicroButton.

5.4.2 brought a revamp of the old raid browser making it cross-realm, but they kept it at the same obscure location with no visibility.

This little addon corrects that oversight, making it readily available

If you want to get rid of the Blizz Store and its microbutton entirely instead of re-purpose it, check out StoreBeGone!
Do not use both addons together, pick one or the other.
