option to switch between calendars (hiding all calendars but the one selected) by both using buttons and shortcuts.
this is doable in Fantastical.app, but Fantastical has an atrocious UI.
i wanna be able to do forecasting based on the data i entered! and maybe the calendar can fetch data from other applications.
it's data, it moves!
it would be nice to add 'action tokens' somewhere on the GUI, and instead of copy pasting the same event from last week, you can drag and drop an action token from the token list to the day area.
so, we add all this data to the calendar and the only view we get is a mimicking of a printed calendar: the filtering options are non-existent or not really useful.
i wanna for example being able how much time i spent on activity x, based on the entry's name, calendar, etc.
i wanna have a better view of a project timeline, how much time i still have, etc.
if i am entering data, i wanna be able to manipulate how to see that data. especially because the data on a calendar is often very precise (date, time (start–end), location, note, attendant, availability, and so forth).
