Add feature to save a search as a new tab

There was a feature in PT that allowed us to search for something in the search bar including advanced features like filtering stories by created date, status, only stories without owner and things like that. And after that, there was an option to save this filter as a tab.

I used this to create filters for my team like:

Stories that need a frontend developer that don’t have an owner yet

How many points somebody finished this year
