Mark me down as another user who would very much like to see this feature in future MarginNote versions. It would certainly be quite welcome for users like me.
Thank you for considering this.
PS-I’m somewhat alarmed that MarginNote only has one developer. You put together a fine product that we’re grateful for, and it would be a shame if it unraveled because of such limited manpower. Is there anything that can be done to add more developers to your app? I confess: knowing this makes me quite nervous about the long-term stability of MarginNote. I hope this can change so that it can become a more stable and reliable app.
