While in the bookmarks sidebar, sometimes I want to jump in to the Manage Bookmarks area to perform more extensive adjustments to the area I'm in. For example, I wanted to select multiple bookmarks and move them in a subfolder -- an impossible task in the sidebar.
However, when I use the Bookmarks menu > Manage Bookmarks command, I'm brought to the root level, rather than the area where I was working.
As solution, I suggest one or both of the following:
Add a Manage Bookmarks command to the context menu shown when right-clicking a bookmark/folder in the Bookmarks sidebar.
If you select the Bookmarks menu > Manage Bookmarks command while the Bookmarks sidebar is open, you will be navigated to the selected bookmark/folder.
