I am running InDesign 2017.1 on a 1920x1080 monitor. The toolbar icons are quite small, but still usable, except for the ones dealing with color and stroke (lower left corner of UI). The mini-icons are trouble for old eyes and hands. I have tried changing the Windows text size setting to 125%, which improves the mini-icon situation but bloats the whole UI, reducing the work area. All I really want to do is make the color/stroke jumble easier to navigate and use. Everything else is fine as is.
