Hi JohnJohnJohn,
some of that I knew already others are new to me. Thank you for investing the time to this rather exhausting link collection. (I have been in software development for quite a few years and know that there are only good developers on the market. You can distinguish two groups: the ones seeking a job and the ones having a job.)
What I wanted to convey is: What is a good GUI depending on the product? BIAB was and is still intended also to be used on stage. So a good GUI for desktop use may and will deviate from a good GUI for use while playing on a stage.
It boils down to the question: "Boss, could you pay more?" and he says yes: "Of course, I'll give you a raise of one dollar per month." Not the answer one wants to hear, but it is more than before.
So if one says "make it better" then please give an example; may it be in writing or drawing or by other means of just saying: "You didn't do a good job."
