It really rattled my cage when Gnome terminal was changed in 3.14 where you couldn't set titles on your tabs. I had a hard time finding a good way so I found a method that worked and made a bash function. Add this to your .bashrc

set-title my-title

set-title my really long title with spaces

I hope I made someones day with this one.
