I made persistent_undo as part of Google Summer of Code in 2011. Very grateful I got to do that (and for the mentorship of Bram Moolenaar), and I'm so glad that this became part of your essential workflow. I also can't live without it at this point.
Thank you so much! It is very much appreciated and I don’t think I have any cases where I wish it was better. It works exactly like I expect and does what it says on the box.
