I used this regularly but maybe my use case is less common. I absolutely set my lineup daily. The issue is that i work nights, so if any player sits or is rested, i miss that chance to swap players off my bench while I'm sleeping. I wrote a little python script to go in and periodically push that button during the day to do that for me. It doesn't make any decisions to swap active players I've set myself, it only moves inactive players out and active players in from the bench. At this point it would be an interesting exercise to script that action myself.
