It would be nice if there was a non skinned version of the program. The current version 15 light skin does not respect the Windows settings, e.g. the Window caption is white, even though I have set it Blue in my Windows settings.

Also, the UI is slow and flickers - try to resize the Preferences window and you will see what I mean.

I assume you have set the "Light style" to "None" for the "Color theme mode"? Beyond that there are no options to change the colors.
