With so many different buffs in the game with different durations and added premium bonus it's really hard to keep track of them all. I'd really like to see all active buffs at my screen, like this:
That's a screenshot from another game. Here you can see all your buffs and their durations (P is for permanent). These mini icons sit at the bottom right corner of the screen until they have like 1-2 minutes left. Then they move more to the center of the screen so they are easily noticeable. Super helpful thing, allows to keep track of your buffs and renew them when needed.
