While I was working on D10797 I had some more ideas to improve the review side panel. I'll put them here (sorted by estimated difficulty of implementation), so we can discuss if they are worth implementing.
EDIT: I am also including bugs reported by others
- [ ] Open popup notes when double clicking an entry of the review side panel
- [ ] Auto-expand all tree elements in the side panel when the panel is first shown. (As it happens when group by author, group by page is toggled)
- [ ] Do not collapse tree elements when adding a new annotation Bug [380092](https://bugs.kde.org/show_bug.cgi?id=380092)
- [ ] (Maybe) Add button to collapse or expand all elements Bug [377024](https://bugs.kde.org/show_bug.cgi?id=377024)
- [ ] Fix Page and Author tree elements are collapsed at every change of page when "Show revisions for current page only" is selected
- [ ] Show small triangle to point to current page (as it happens in the ToC)
- [ ] When the text in the search filter matches an author or page,Related to the previous. showHighlight annotation in the child nodes,document when its entry is selected in the side panel. i.e. the reviews entry made by that author / on that pageBug [323454](https://bugs.kde.org/show_bug.cgi?id=323454)
