Add tap actions for other views

On my tablet I have room for 2 days in the main view. It would be nice to have tap-actions, so an other view or tab can be opened for the whole week, of at least multiple days.

A general tap action would also be nice allowing any service to be executed when card or even calendar entry is tapped. I use calendar to show all kinds of todo‘s for my house and tapping would allow me to attach a ‚done‘ action to it.
