add in a feature that can sort the favorite bar, this is important especially more fav bar may need to do sorting so that can see / find easily.

The light dates works against the concept of a quick glance for measuring the upcoming.

I find the location suggestions (Powered by Google) to be quite intrusive when adding or editing calendar entries. The majority of my events are internal rooms/offices and don't correlate with any nearby public buildings or addresses anyway - a simple option to remove these location suggestions would be helpful.

Keep up the good work!

It would be really convenient to be able to mark a task as done/completed directly in the notification.

I would like the option to hide passed events and tasks separately. Specifically, I really enjoy how the agenda widget hides events when they are passed. However, I would prefer tasks remain visible until they are checked off. There's nothing more annoying than forgetting a task because this time it was set to had passed.

A special calendar which reads out contact birthdays automatically. The age of a person should be displayed, too.

I would like to speak my appointments or tasks, while driving or take a bath with wet hands. So important notes would make sense to handle in tasks.
Because it's not easy to develope an user friendly voice input method, also a merger between BC and another app would help (as example "Speak your appointment"...kommt ja auch aus Berlin ;-)
This feature would also very helpful together with wearables, which going to became an hype for sure.

Would like to toggle transparency level of the widget.

please add warning message when entering event with past date or time... or when editing existing one.
i often accidently enter new event on wrong day :-D
thanks

Ability to copy an item after dragging it around in week (and day view).

In week view I would like to bring the calendar buttons in a different order to display the most used calendars on the left side.

When in week view, I would like to be able to tap on the date and have it switch over to day view for that particular date

Could you please give back the option to choose in which hour we want the reminder for birthdays? I would like to have a reminder at 17 hour after work when I can call.
I would also to have reminders for allday events in the morning after I wake up.
