Great to hear that the toggles are coming. Keeping my fingers crossed that you’ll get something awesome done with the sidebar as well!
The fullcalendar view of now is not super user friendly on mobile devices since “hover” is notoriously hard to handle there. Also the month view becomes to cramped and then people need to manually switch to the list view, where again the hover functon doesn’t really work on mobile.
The way you have made the calendar month view with sidebar switch to a compact calender with the events underneath is really really good. If you can nail this concept with fullcalendar then I’ll switch, since it seems like fullcalendar loads faster.
