Hero Roster Tabs

I would love to see tabs when I click on my heroes. One thing I really dislike is having my feeders and trainers all on the same roster page - Sorry Aife but you don’t belong on my roster. The first tab is for my locked heroes. The second tab is for trainer heroes, and the third is for all heroes I claim. If I lock a hero on the third tab then it automatically moves the hero to the roster tab. When you level up it would be similar to the costumes where you click on the hero and level up, then choose the tab you want to level up from (trainer hero or claimed/feeder heroes). If SG wants to limit our space like they do with the roster currently then we could use gems to add additional roster space. Or, when we level up it could give us another space or two on each tab.
