Add Calendar Feature as in Journler or MacJournal

One viewer requested this feature already and I would like to second it. I am transitioning from Journler which has a calendar. I find it a really good to have feature since it gives me a sense of how I have worked over time. The other user referred to the calendar feature in MacJournal. In any case, I would appreciate this feature.

Something like this may be implemented in a future version of DEVONthink. Cheers!
