In Ninox for Mac, there is an invisible border in the top area of the Finder window. Below the red line, you can drag and move the window. Under the line, you can't. Beacause it looks like one area, I often click on the lower part, just to see nothing happens. I'm using the Mac for 30 years and as far as I remember, Ninox is the only program having this issue. Please fix it!
Of course, "Below the red line..." should be "Above the red line..." ;-)
Yes, that is a good point.
We are working on the UI and have this on our list.
