Sure, I want to have selections that are tab-specific. Going something like this:
- When I leave a sheet, a new bookmark with those selections is created.
- All selections are cleared.
- When I enter a sheet, the bookmark that was created is applied.
Which works nicely, but if multiple users are switching tabs at once, then multiple 'latest' bookmarks will be created and will conflict with each other. This is why I need the bookmarks to be user-bookmarks and not document-bookmarks.
