Honestly I don't really want to implement anything like queue for actions. I understant that the game right now is pretty repetetive, but I hope the addition od passive gain based on your max will help with that, since you wont have to repeat the same runs over and over again, and you will be able to just wait and than do run, which will take you further than the last one.
But if this doesn't help, queue might be something I would consider.
