Uhm... not sure if this is a bug or I just don't get a new feature:
Recently ST3 added "()" to its title bar. Why?
Looking at my title bar, it looks like that's where the project name is listed. Just pulled up my ST2 install and it also shows it there if there is a project, but not if there isn't. So it's a bug, you are understanding things just fine
Great. Where to report it so that it is actually noticed?
edit: I added an issue: github.com/SublimeText/Issues/issues/142
