The pet for Party member 1 is good, but party member 4's pet is way out of sync and I can't fix it w/o breaking the arrangement for party member 1. I tried rescaling the pet frame and adjusting growth distance, but neither come close to getting the pet frames where I want them. How can I anchor pets so they appear below the member's name?
2) How do I hide the XP/Rep bar? And the empty casting bar background?
For #1, my best guess would be that scale, growth distance, and theme would need to be identical to the party for it to work perfectly. Not sure why you can get it close with the two though, they should cover any contingency.
#2 is under the player frame options menu. The options are pretty apparent, alt-click your player frame if you don't have that disabled.
