I currently have work and personal Trello accounts to separate my work and personal boards and notifications. I have different profiles using Chrome which allow me to easily switch between my Trello accounts by just going to my work or personal browser profile.
I also use the Trello Mobile app on Android, but it is a pain to have to log out and log back in to my different accounts just to see me work or personal boards. It would be great if there was a way to have both accounts registered with the mobile app and be able to easily switch between the two.
