Great questions. I would love to see “folders” where I could tuck heroes. For example, my “have’m but no plans for them” folded with Guardian Owl and friends.
Like you, I would like the option to show the bench ignoring the team designation. A simple toggle ther would be great.
I’d also,like displays to be simplified. Why, on the level up screen, show the Favorite locked heroes at all? It just adds a lot of scrolling.
