When I tried to edit an entry in the desktop app without active internet connection, the app shows “An error has occurred: Failed to fetch”.
So, it would be nice if desktop app allows for offline edition (make changes to the entries). These changes can later be synced once there is an active connection.
This feature might not be central to browser addon or web-vault. But, I think the desktop app should have this option. Not sure whether this feature should be implemented in the mobile app too.
In any case, this feature request can be evaluated depending on the security concern for allowing offline editions - both technology wise and use-case wise.
