Adding a button to display the side agenda when adding an event
I used to like in BC 1 Pro the side agenda when adding an event. In BC 2, although you can slide out an agenda with a swipe, if you use gestures instead of three buttons, the gesture doesn't work. If they added a button between the calendar account options and the color button to display the side agenda then the problem would be solved.
Try activating the sidebar at start in the settings -> views -> create & edit -> when creating/editing events show.
