WowAce

Seems to have a problem with co-existing with SilverDragon Addon

Minimap Icon does not showup when SilverDragon Addon is running

Suggestion:

Add a checkbox to show:

1) Mounts in this world only

2) Mounts in this Zone only

First suggestion logged here: https://github.com/WowRarity/Rarity/issues/428

The second seems obsolete; there's already a checkbox to only display items in the current zone. It filters all items, and not just mounts, but perhaps that's sufficient?

As for SilverDragon, I'll need more information. But it doesn't seem like something Rarity could affect, so you may want to take it up with them instead :)
