I conducted another round of user testing. These tests were a bit more formal than the first round. There was still some confusion due to the testing environment, but overall these tests were much more productive and provided more valuable feedback.
Participants and my mentor made some suggestions for changes, mostly having to do with accessibility and usability:
• increase clickable area for certain icons
• increase size of search bar
• make sure back button location is consistent
