Help finding app

Looking for two different apps, hoping someone can please help finding or recommending something as google doesn't seem to bring up anything.

1) Something that measures how long my mba takes to run down from a full 100% charge to 0%. Not like the inbuilt utility that tells you how long you have left more to establish a record of run times.

2) I don't know if this is possible but on windows I used to have the task bar set up so that when you click on a programs icon it cycled through the apps open windows. The same as what cmd + back tick does, but to happen when i click on the dock icon. I see hyper dock but don't want to spend the money unless it can do this.
