Show window title on application expose

I'm noticed that when you expose the windows for one application (for example, I click two times on the LibreOffice Impress icon with 3 windows opened of that app), the windows are hard to identify becaue I only see the window content.
If I have for example 4 windows of Writer with text only documents, identify each other is very hard.

Would not help that the windows will be shown with its titles near?

Probably a good design is show the window title over and bottom of each window, over a semi-transparent rectangle, maybe adjusting the font size depending of the amount of windows being shown.
Or like GNOME Shell do, with the title outside the window (avoiding problems when you have small windows and the title does not fit in the window.)

Would this helps with same app windows identifying, what do you think?

Thanks in advance and continue with this excellent work!
