Use a separate Google calendar to sync Nimble tasks.
You can create multiple calendars within your Google Login, why not create a separate Nimble Tasks calendar to sync Nimble tasks. Of course, keep your master calendar to sync with Nimble calendar events. Just a thought.
We will review whether or not we can sync Nimble with Google Tasks. We will have more to share in the future.
The Nimble Team
The key request here seems to be for Google Calendar feed. See implementation in e.g. Todoist, Highrise, Trello, Liquid Planner and most major task / project systems. EVEN if you want users to stay within Nimble for task planning / follow-up, Google Calendar / ical / CalDAV is going to be needed, and lack of it is a turn-off. Thanks!
