We should have a "Highest streak" counter in our profile.
That"s it. The title says it all.
I'd also like to see a full, dated record. I just got to, I think, a 159 day streak and lost it this weekend. I can clearly see that I didn't get to the 160, but I'm also not 100% sure how far I had gotten, if it was 158 or 159.... It'd be nice to have a calendar or something set up to show our work, maybe even what we'd done each day, and CERTAINLY the number of days in each streak and the date between which it was held. It'd be a great way to be able to look back and see one's progress.
It'd at least be nice to see this info in our activity box. Something like "USER Date: Got a 159 and streak!" Or, even to just have the Activity box actually give a date vs. "3 days ago" or the even more vague "one week ago."
