Autocomplete location from history
I miss the way location autocomplete used to work in BC1: after typing two letters, a list of suggestions from the location history was presented.
I work at a large company with dozens of conference rooms, too many to fit on one screen when using the history manually. It takes a long time to scroll and choose, now that the autocomplete uses Google search instead of my own frequently used locations.
On the other hand, the Google autocomplete is helpful when I add a personal event that might be at a restaurant or other public location. But 90% of the appointments I add are in private conference rooms for which the Google results are not relevant.
