Hi,
probably this feature is already there, but I missed it 
Especially for follow actions it would be nice to group DMX fixtures so have a bit more control about which lights follow another one.
In my case I have 2 moving heads, a light bar and 8 spots.
In a follow action (e.g. flashing) I would like to have this order:
Moving Head → Light Bar → Moving Head
Spot 1 → Spot 2 → .. → Spot 8
These 2 flows should run in parallel means Moving Head 1 and Spot 1 start flash at the same time.
Moving Head 1 + Spot 1
Light Bar + Spot 2
Moving Head 2 + Spot 3
Moving Head 1 + Spot 4
Light Bar + Spot 5
Moving Head 2 + Spot 6
Moving Head 1 + Spot 7
