The amount of times a given power up is helpful, but sometimes I wonder if I marked my power up, or if I forgot to mark it. By showing the last time the power up was completed I will know if I marked it or if I forgot to mark it. This also seems complimentary to another feature request for the ability for an individual to mark the time/day they completed a given power up, which I also like in the case that I had forgotten to mark it.

Really enjoy what you've done so far. Looking forward to future updates.

Thanks!
