in my opinion some recent GUI changes have been bad moves. There is plenty space in most of our screens so I see no reason for what appears to me a bit obsessive minimalism. The new dropdowns are cumbersome... but also, have you ever seen a program with two identical buttons side by side but with different functions?
Sorry, friends, YOU NEED TO start taking seriously a redesign of the GUI. This is a crucial aspect in software development and you have been almost disregarding it since years. I know that you are reluctant to radical changes, me too, but there are many thing that can be done without driving your users crazy.
With all my respect (you know that): Design is not one of your skills, admit that you feel happy diving into endless code windows and frightening things like LaTex. Admit that you think that users don't care so much about the beauty and often get used to the bumps of the road. But may be your are wrong at this point.
I suggest you to take the money you obtain in the next 4 professional licenses and pay someone. Please, hire an expert in user interface development, and tell him/her ask your average users (around the world, not just at home) before choosing.
Example: Years ago I suggested you to modify cursor icon appearance according to active mode or tool... You did right but only while dragging markers on photo... but why only then? Dont you see it as a huge advantage in many other circumnstances?
Kindest regards
