I'm using a large, hi-res monitor, and have increased the font size for everything I could in DOpus.
Works a lot better than decreasing the resolution on my monitor.
Problem is, I can't increase the font sizes in the FIND panel.
I have to squint to see and confirm what I'm typing.
It uses the system dialog font.
AFAIK the only way to change that font size is to set the system to use "large fonts" or "high DPI" mode. (The name of it and how you turn it on depends on which version of Windows you're using.)
it helped, but screwed up the appearance of several other things
going back to original dpi
