Is it possible to show a cell footer only for cells with a given tag? I would like to add a button in the footer that trigger a given action only if the cell metadata contain a specific tag. I know how to add a footer to all cells of a given type, but I am not able condition the rendering of the footer to the existence of certain metadata. Is this a feature of the jl-enhanced-cell-toolbar extension?
For others facing the same problem, I was able to add a footer to cells with a given metadata by overriding the default StaticNotebook.IContentFactory class.
