In order to add events at specific times via clicking the calendar, you have to donate money. If you try, you get a popup stating that "These dimmed out options are extra features I spent a lot of time developing. To unlock these features, contribute ANY amount in support of my work." I initially thought it was a bug until I went to the donate page, lo and behold, under the extra features "Create events by clicking in the calendar" So, in short to add events I still have to go into google calendars to add events...This entirely defeats the purpose of even having the addon.

This is a real shame because this is otherwise a very solid add-on, but the inability to add events is a game breaker for me. Especially since it was a prior feature.
