Hi 40Tech team! Brittany from Behance here.
Thanks so much for the great review. I just wanted to quickly address a few of your “negatives”:
1) We do offer an export of all data, via the “Data Download” link (this is located under the Resources tab)
2) Calendar, offline, and drag/drop are all features we’re batting around for future upgrades.
3) Customer service is something we’re constantly striving to improve; if you ever need an urgent response, try contacting us via Twitter (@actionmethod).
All in all, this feedback is great — as a growing business, we really rely on suggestions from our users to continually hone the product. Keep ’em coming!
