Please let us increase the font size and tool-icons in all desktop applications, especially Indesign.
Photoshop has something like that, but still the UI font size is not large enough for comfortable view on a 27 inch iMac or a retina MBP.
How could it be that the best designsoftware doesn't offer good scalable graphical user interface?
Direct your feature requests to Adobe through their feature request forum. This is a user-to-user InDesign forum, though someone here might have a suggestion to help you.
Retina Displays are supported from InDesign CC and newer, not up to CS6.
