Thanks for adding this function. It is quite helpful to see calendared items in the timeline view. Turning on linking to my gCal was a breeze, though I'll admit I didn't think it was working properly when items didn't just automatically show up. It might be less confusing if the act of linking automatically included a synchronization, so items would appear, or at least display an indicator that it is linked, but unsync'd.
This is probably a big ask, but we use several calendars. The ability to link to more than one would be helpful. Thanks again. It is great to see all of the parts coming together.
