@reckart I'm sure the results list jumps because the sidebar is refreshed when a new document is loaded. I have two ideas to solve this: add some javascript because in js we can to my knowledge change the scrollbar position, I would save it when the result is clicked and then restore the position.
Another idea is to just not refresh the sidebar, I would flag the sidebar to not be refreshed when all children of the annotation page are refreshed on document load. Because I just learned that you can set component metadata, I would add a flag as metadata to the sidebar. The second idea needs a check in the corresponding webanno method that refreshes a page. What do you think?

You wanted to implement the tab for the new "curation" sidebar panel such that it shows only if the user has curator permissions. Would showing/hiding that tab still work if the sidebar is no longer refreshed?

Since curation is a project-level permission and we switch between documents within a project... I guess it would?

What about if documents are switched e.g. in active learning mode? Does that somehow rely on the sidebar refreshing behavior we have right now?

I think it makes sense to not refresh the sidebar on switching documents, but maybe some sidebar panels need it and then they might have to "listen" to a relevant event and refresh themselves.

This has been fixed for the case of clicking on a checkbox in the lower parts of the search results. However, when clicking on a result causes a switch to another document, this causes the whole page to re-render and in this case the sidebar still jumps.
