Tiny UI elements on high DPI/4K display

[Ahto]

I upgraded from 2017 to 2019 to find out with disappointment that there are no improvements for high DPI displays -- categories check boxes and thumbnail badges are tiny on high DPI display (fonts at 200%), mine are less than 2mm in size and difficult to hit with the mouse. Other UI elements look OK.

Are there plans to improve this?

There many improvements for high-dpi screens in both the 3rd party UI toolkit and IMatch itself. Although 200% scaling of everything is quite a lot. What kind of monitors do you use to need such a super-high scaling factor?
I use IMatch on systems up to 175% scaling and I know there are even users out there who need 250% percent scaling of everything, because they combine very small screens with very high DPI...

Did you enable the options to adapt IMatch to high DPI monitors? Since you did upgrade over 2 generations in one step, many of the prompts and questions normally displayed will not apply to your existing configuration.

Did you perhaps in the past use one of the "scaling" properties for applications Windows offers? This will work against the automatic adaption of IMatch to high DPI monitors. Right-click on the shortcuts you use in Windows Explorer and check under Compatibility > High DPI settings.

Thank you, by setting icon and tree icon size to "large" under preferences the issue is solved. I was not aware of the settings and assumed the program will do this automatically as check boxes in Current categories tab were already in correct size and tiny were only check boxes on Categories tab. I use Dell P2415Q 4K monitor with is quite high resolution 24" monitor and much prefer it to typical 27" monitor due to that higher, smartphone like high DPI.

IMatch users use hundreds of different DPI settings on hundreds of different monitors. Users have different preferences. Hence IMatch does not everything "automatically" but leaves users choices.
A 144 DPI panel looks really different on a 32" monitor compared to a tiny 22" Notebook screen...
