This post maybe will be fantasy for some but I like to make everything in mikrotik perfect specially with winbox.
There is a bugs in winbox windows title specially when title become longer than window's width as you can see below
The close [x] and [_] buttons are removed because of long title name. I think the title must be dynamic in length based on windows width.
as fixed image for the windows below
it's just an idea and hope to get some attention about it
regards
