Adjust scaling factor in preferences
From time to time there are support requests in the forum, where users (not me, Idon't have one;-) have trouble with the resolution on high resolution monitors, first of all with windows 10 and OSX Sierra ("icons are too small" and so on).
I know you can MuseScore start with -x option for scaling (which only affect the icons, not the font of the menu entries).
While we know too little about details of the monitors for a solution, I wonder if it would be useful (respectively possible) to have - in sense of usability - an option for adjusting the scaling factor (or dpi settings) in the "Preferences"
("Blender" seems to have something like that to adjust the dpi, when I understand this correct: https://wiki.blender.org/index.php/Doc:DE/2.6/Manual/Preferences/System.
Note ( wasn't aware of that): you can adjust in preferences the icon size (but an item for scaling factor could maybe useful), but maybe there could be something similar to Blender that is affect also the size of menu entries (in sense of changing the dpi solution). But I'm not a programmer ;-)
