Quick answer, no.

There are couple of ways to make it work for now but they are patches:

• One would be to share a Google account with your partner so you both have access to the same data.
• Another would be to store the file somewhere where you both have access and then import/export the file every time

Why haven’t we implemented this yet?

Maffin is not built for concurrent use. The data is local-first which means it is stored in your browser and whenever it changes, it gets synced to your storage. This means that if someone else is editing the same data, this data would be over-written. We don’t have a way to avoid this yet.

Another reason is security. Maffin requests permissions to Google Drive to access files there that are created by Maffin. This means that if someone shares a file with you in your Google drive, Maffin won’t have access to it.
