InCopy needs to have 125% and 175% scaling support.
InCopy is my favorite word processor and works perfectly with InDesign. The one issue is not working properly on 2880x1440 displays and its is due to the lack of scaling options.

The 125%/175% is a big issue for my company. This is a sought after detail that should be implemented.

This holds for InDesign as well!
