I have big doubts that this is the case. Qt applications have not possibility to change resolution for entire system. This is Mac feature. Setup your Mac properly.
I didn't say that this was a bug of Valentina, or the Mac. That is what I meant with "I don't think is a bug", simply that the software wasn't optimized for the Mac. And since according to you the Mac is a 2nd class citizen, I accepted your answer (especially since I use both Inkscape and Illustrator that seem to use this functions in a similar way). Therefore, it seemed logical for me to infer that if Valentina considers the Mac a second class citizen it was Valentina not being nice to the Mac and not the other way around... wouldn't you think?
But you are correct, and in case that it may be helpful to any other 2nd class citizens as dumb as me... , the accessibility features (which I didn't know were on) were using the zoom shortcut, and my new Logitech mouse was setup to use the middle button for Mission Control (I just use the trackpad for that). So, thank you. It will definitely make a difference.
Not really. You are to aggressive to cooperate with me.
I don't see how I am being aggressive, I haven't stop apologizing since I got here for taking people's time and being a pain with questions. Also, I added emoticons to make sure that what I said was understood and not taking it personally; Maybe it wasn't. As I keep repeating, I am new here and don't know the "neighborhood" and who does what, I just asked for some help, try to give some feedback (tricky thing to offer, I know) and offered to contribute into the "community" if, and in what I could, not necessarily you in particular, but in general. Didn't expect to receive dismissive answers though. You said to me before, in another post, "This feature has low popularity. Most people do not understand it and don't want to contribute to it." but I did, and I perfectly understood your point in not wanting to invest your time and effort in some feature that people may not use, but I wasn't forcing you to implementing anything, I just tried to explain why it would be a useful "feature" that would make the software more usable with what seemed to me (and pardon my ignorant assumption) not a big investment in programming effort and just a small detail. I didn't think that I have to prove that I wanted it desperately enough rather than express a logic for it's implementation, and I fully recognize and understand that you have a better perspective of the development than I could possibly pretend to have.
Anyway, I am sorry if my feedback rubs you the wrong way and you find it aggressive, it wasn't my intention. I guess I just keep it to myself.
