@marco 1) What do you mean by "Open appropriate event handler code when double-clicking on a control/view" ? You mean that double clicking on a control/view in Design should open the Code Editor for that object?
It's like Visual Basic (1-6) on Windows and ASP.NET WebForms (in VS) used to work.
If I for example double-click on a Button control in Design it goes to the code editor in the Action event. For a TextBox it would be TextChanged, etc. Every control has some sort of a "most used" event. After I've finished entering the code I would then want to return to the Design focused to the control I double-clicked on, so that I f.e. can do some other work on it or change the control next to it.
For me that is a quick and convenient.
@marco 4) We already fixed icons issues in our build, unfortunately there is very little we can do about the blurry text because Apple changed the antialiasing algorithm in 10.14 and the result is that the text is less clean on non-retina displays.
I understand, but maybe a setting to change the font for those text would work, as the coding font is less fussy in my case.
Also the Private indication for functions is almost impossible to read; see attached example.
I understand that you're bound to what Apple does, but maybe some fixes may work for non-Retina screens.
