I think that we are reaching a reasonable compatibility stage with windows applications. However, there are applications that ways get progress and regressions in different areas. [Idea] So, I was figuring out, if there is a way to automatically test applications, against Wine. There should be a way to every new patch, be tested against a set of applications, and it automatically report the execution log to wine developers. In this way, the regressions could be reduced, and controlled more precisely.
