Also note: on desktop versions, once you get a board set up with the views / filters you desire - you can right click on the board name and, “Save View as Default”.
Then, if you use a board and end up “messing it up” - changing views, adjusting filters, whatever - you can right click the board name again and “Restore Default View” to go back to your original setup.
I use this all the time - I get boards set up for my workflows, then in the process of using the app, “mess them up”… I love being able to reset them to the default, the “saved Search” feature in many ways.
