Select the event you want to prepare and “drag and drop it” to your Desk. This will create a new card, connected to the event, to work on.
Even if you remove the card from the desk you will still be able to find it in the Calendar event. All prepared events have a link icon in Mindmesh Calendar.
Meeting preparation cards are also accessible in Google Calendar.
Pro tips *
