Is there any specific reason why federate controls were not included in Gerry's Mach 3 Aqua screen set?
I haven't used it in many years, but the picture on my website shows a FRO slider and DRO.

And no, nothings changed, using FRO over 100% can potentially cause issues. I don't recall exactly, but it may be over 150% where it';s more likely to cause issues?
