[feature request] better identification of each tab: allow having custom app names or titles

[pedro-nonfree]

So, with the feature of sandboxing a Service URL you could have N services running the same URL with different accounts with the same application. Woah, this is so GREAT!

It would be nice to allow overriding the title of the apps, so imagine there is a very famous app and you have two phones, one for work and another one for your private life; then you would have: "myapp home" and "myapp work", right now, both
appear with the same title

And I hope the title name allows having emojis :)

I see a UX problem to solve, if no one has a better idea, just add the title/name input field to be collapsed/hidden like the sandbox thing
