Please allow us to detach the cast bar from the target frame. I usually like to have this moved around so it’s easier for me to see when I need to interupt something. Not all of us look at nameplates.
Regarding the raid frames, as a healer I like to have different spells in each spot of the frame for each target so for example, Riptide Top Left, Earth Shield Center Top, Dispels Middle Center etc. Allow me to dictate what spell goes where so I can make it consistent rather than just having it in the bottom right hand corner and it grows to the left in a random order.
Again on the raid frames, please allow us to sort by role and by group at the same time. At the moment, you can only have one or the other. I would like the option for both as I prefer to have frames go Tank, Healer, DPS, DPS, DPS. This can be done in the party raid frames but not the actual raid frames.
Finally, please set the anchor point for raid frame growth. Currently it only goes downwards when you expand in the edit mode for a larger growth size. I prefer it to grow upwards.
