### Acceptance criteria 

* **In project settings,**

* Rename "Backlogs" to "Backlogs and sprints"

* Add a new tab, "Sprints"

* **The the "Backlog and sprints" page,**

* Rename it to "Backlogs and sprints" (both plural)

* Show the "Start sprint" button on all sprints that are in planning

* If there is a max limit set (see open question), then 


### Open questions

* Should there be a limit on the number of active sprints per project? 

* If yes, should this be a setting for the project admin?
