I use reMarkable (https://remarkable.com/) everyday, with every customer or vendor to take notes, sketch out options, and to take measurements for windows and doors. It is a wonderful tool that I have been using for years. I do drop files using Google Drive, manually into job documents.... but I would LOVE to see an integration between reMarkable and JB. Please do not hesitate to reach out and I can show you examples on how I use it.
