Feature description

An option to share checklists as simple text.

It could be implemented using a radio dialog to choose between the different formats for sharing but I don't see any reason why anyone would want to share notes in JSON format.

Why do you want this feature?

So I can share it with people who don't use Fossify Notes e.g. my security guard.
