I've committed a fix for the auras. The aura container frames were not parented to the main frame so they did not take the scaling of the parent frame. That caused calculations for auras per row to be wrong. The containers are now parented to the main frame and now take proper scaling into account.
Due to this your auras might be smaller than they were before, but they won't go beyond your unitframes anymore. This makes the 'snap' option a lot more useful as well.
frame to 75% and aura to size 24, than snap. Works great. Thanks.
What about an global sizer for the Frames (not raid or group) This would made my day.
Thanks for your great work.
