On my healers I regularly use old style wow raid frames enabled by scripts simply because they allow me to split raids up exactly as I want them (particularly being able to split melee dps from ranged dps). This helps maximise the effectiveness of spells such as chain heal and I feel makes me an all round better healer than when I heal with other raid frames.
Up until now I’ve not come across any other raid frames which are able to sort raids by role including the melee and ranged divide and wondered if anyone else might have an idea of anything that can do this? I feel a bit like a dinosaur relying on scripts that get the raid ui to be as it was in classic 
All ideas/suggestions appreciated, thanks.
