If your booster slots are already full, it would be nice if we could use a new booster right away. Until now, the only options are trade with an existing booster, trash it, or buy an extra slot.
So I'm suggesting a "use this booster now"-button.
If you're winning boosters via derby reward (if you can win all horseshoes there are 2 columns only with boosters), it's heartbreaking to trash them, when you're already full with other boosters.
