OK, I just asked Thomas to send me the email thread about his problem with SMC. His communication was with William Stein and Harald Schilly, and related to lost bits of a jupyter notebook that were not even recoverable using the revert button or the backup utility, plus bits started disappearing or re-arranging again. On 4 November, Harald replied to him with the following words: "Hi, this sounds like a real bug we have to fix. Getting a history and collaboration working with jupyter notebooks is not easy.", followed by a message by William Stein on the same day indicating that a fix would require a major rewrite of Jupyter, and suggesting a method to use standard Jupyter within SMC. Unfortunately, Thomas overlooked that suggestion and didn't try it out. Still, the problem of disappearing or re-arranged code cells within a worksheet reminds me of problems I used to have with sagews, but I haven't experienced them with jupyter so far. If this is a particular problem with jupyter notebooks within SMC, and if it re-occurs, perhaps this way of using jupyter should be discouraged in favour of using pure jupyter or jupyter kernels within Sage worksheets. If instructions are available how to do this, I'd be happy to try it out.
