Change to Existing Work as Selected Work when Existing Work is Entered
This will be fixed in the next version. The bug (which causes the observations in both your posts) has actually existed since v1.30.1, released March 2025.
ReleaseNotes
Remember Where in the Tree I Was When I Click on a Position Etc.
This is now implemented and pushed to the git repo; will be in v1.35
It is a good idea to have it take you to the instance of that record you were on most recently. I can implement that, but I also want to point out that you can click the previous/next buttons at the bottom to cycle through the tree nodes for the selected record. That should make this less annoying until this feature is released.
Think about it this way. Some people don't want spaces in their filenames, they want underscores. Other people don't want spaces or underscores, they would rather have neither. That's what the setting is for. It's not intended to be an author separator. An author separator feature would be a new feature request.
