i really like the idea of <- prev / next -> at the marketplace for super facilities and co-op quests but i think it needs a little tweaking.
it used to be the super facility always started on Buy Super Products and now it remembers what you were on last. personal preference maybe, but i like it when it always started on the Buy tab
for co-op quests, it's really hard to find a starter sometimes so you click on 29837 people anyways. another color? lol hope not. but it would be nice to have an indicator of who had co-op quests - maybe a pink nose
for both of these two functions, maybe wrap-a-round would help to prevent a lot of clicking to get back to where you started to go the other direction
