Utter BS. Not being able to manually override event details, add images, or tags without them being deleted in a sync is a total waste of a calendar.
On first glance this plug in was beautiful... and if it could do the above it would have solved all my event problems. Reading the FAQ replies from the MANY other people having the same issues 6 months and longer ago, shows me development isn't exactly working hard to remedy the issue. And the snarky reply "thats just the way the calendar world works" was totally not warranted to any user. Because the calendar world does not need to work that way, it only works that way because Timely programmed it that way.
