I would like to show a set of pages with a given label in the sidebar. Couldn't find wiki markup for that macro. Is there a way? I tried some wiki markup based on earlier examples, but couldn't find one that worked.
I think, you mean the content-by-label-macro. This macro is not working in the sidebar. There's an open issue for that:
The "related-labels"-macro is working there, but I don't think, that you meant this one.
