I don't know how you want to handle enhancement requests, so I'm just treating them as if they are bugs. Is that how you want them handled?
This one is pretty simple, but in no way urgent. In the title bar, is it possible to display the name of the project after "Construct 2" and before the name of the layout/event sheet? The problem is that when you have several copies of C2 loaded it isn't always easy to tell which is which when you want to set focus, as in this picture. (This picture isn't the best example, since one layout is empty and one has a picture of trees, but much more often it is pretty tough to tell.)
Ideally the title bar would say "Construct 2 - <Project name> - <Layout/Event Sheet name>
