Currently the sidepanel with the links is scrolling together with the main panel.

As not all links are available in the breadcrumbs bar one first needs to scroll to the top to reach the links when the main panel is very long and one is at the end of the page.

Also using the breadcrumbs to navigate to a sibling page is not very straight forward

• hover with the mouse over the corresponding element
• wait for the down chevron to appear
• click chevron so the menu appears
• click the menu entry

It would be nice if the sidepanel is sticky like the breadcrumbs in general or to have an options for sidepanel or layout tag to make the sidepanel sticky
