Thanks for suggesting this!
However, I have a couple of concerns… firstly, this might work well on larger screens, but on much smaller screens it may take up too much screen space? From the image it looks like this might have been on a small tablet?
Secondly, when you go to the quiz activities, these have back/next buttons, so I think that would get confusing for users to have 2 rows of back/next buttons .
In the current sprint we’re doing some work to come up with some suggested designs for tablet display, so can make better use of the extra screen space that is available. So it’s more likely we’d be able to incorporate this idea into a tablet layout, though the quiz button navigation buttons will still be an issue.
Another option could be to add an overlay when the user first installs and uses the activities to show they can swipe between activities?
