I've been testing saving Tags from ManicTime to the Harvest time tracking service. This is a one-way process from ManicTime to Harvest using the Harvest integration.

It would be great if there was a 2-way sync so that if time entries are created in Harvest, or edited there, that this is brought into/updated in ManicTime too. This would allow users to employ the Harvest mobile app to capture time when on site as well as capture time on their machines. It also would help avoid duplicate or overlapping time entries.
