To be able to scale the user interface.
In AI it's possible, but not in ID. Some of the panels and text are so small I can barely see them. It would be nice to be able to change the preferences to small or big for the users preference or blindness.
The introduction of 4k monitors is partly responsible for the increased interest in this subject. But it is valid, and resolutions are only going to increase.
My work essentially revolves around three apps: Photoshop, Illustrator and inDesign. And invariably i have to use all three at once. Photoshop and Illustrator have the ability to increase the size of certain UI elements, which i use. But when you're flicking between the three apps, it can get confusing when certain items in inDesign don't pop up where you expect them to as a result of inDesign's fixed scale. And besides, with less and less manufacturers providing for the professional market thee days we are all being forced down the 4k route. So, if nothing else, for the sake of our eyes :) it would be great, and really improve speedy productivity, if you could bring inDesign into line with the other two and give us consistency. Thank you.
