This is the main reason why I don't swap from FlyPlateBuffs even tho its not updated. If you guys could make the spells you add to the list have specific Size, and by that i dont mean Icon width or Icon height, because modifying the 2 numbers for every specific spell you add its too annoying

I would like so it has a Size or Scale option in every spell so its easier
Also could be like this, instead of that you save specific size for specific categories like:
Stuns: 1.2
Fears: 1.4
Enemy offensives: 1.5
Enemy defensives: 1.5
Would be a nice idea so people could quickly select the size of newly created spells.

Sorry, there are no plans for implementing categories now.
As for "scale", well, users are free to use addons as they like, but I guess sizing spells is not often done. So, there are no plans to implement two different size options: height-width and scale. Sorry.
