[Feature request] Add achieved goals in the goal tab

[alkero]

Hi,
Thanks for the great app.

I'm using the goals tab, and it could be nice to have an option to remove the goals once they are done.

A simple check box or icon on top of the top would do the trick: tap on it to show only the goals that are not done yet, tap another time to see again all the goals, something like that.

Thanks again!
