Move functionality from evolution-alarm-notify to gnome-shell-calendar-server
Similarly to this upstream MR that moves event notification functionality from evolution machinery to the shell (GNOME/gnome-shell#155) the same would likely be needed in Phosh, this would help resolve issues with the notifications from e-a-n taking up large portions of the screen that are not compatible on mobile and generally looking out of place and un-integrated.
There are pending designs for deferrable notifications that are meant to replace the dialog that spawns from e-a-n here: Teams/Design/os-mockups#142 (and attached below) but the functionality to have a sub-selection on a button for alternative defer times would be something that would need to be created.
