No indication on unsave modified files?

I recently just got a trial version for v2. I had used v1.6 and v1.7 before. I remembered previous version will show * whenever I modified a file on the title bar on top of menu lists. In v2 the title show the project name instead of file name as in previous version, it never tell me which files I modified and yet save. Is this a bug or I disabled some options accidentally?
