Allow google signed-out interactions for maps shared with anyone with the link
it would be quite useful to be able to contribute to a mindmup document saved in drive and shared with "modifications allowed by anyone with the link".
The Google docs app allows for example drive-stored docs be edited without having a google account, users appear as anonymous avatars, and this still allows real-time interactions.
This is quite useful for the case of collaborating real-time on a map with people that don't have a google account.
The mindmup document remains only accessible to people with the link, and is not publicly listed/indexed.
this is a limitation of the Google API and not something we can influence on our end.
