First of all:
Please! Please! Get Rid of the "By Universe Pixelmapping". Did you ever try to map Pixelstrips with more than 170 pixels per fixture ? It took me a long time and a lot of calculating to set up. When you´re working with 50-60 Universes via Artnet, its really time consuming to split every fixture in different pixels to make them fit into the universes (smaller example in attachment).
And after that, some wishes for improvement (still not complete):
-Fixture Spanning for More than one Universe !!! (as mentioned above)
-Other Fixures than Lines (Circles,Bend,L, Whatever) Fixture Cutter/Splitter, Warping ?
-Show lowest Adress in Fixture (Red Dot ?)
-Input / Slice / Fixture Mask
-Fixture/Slice Groups (Group Masks?)
-Select more than one Fixture to set framerate, Gamma etc
.....more to come....
