Yes that would be the ultimate goal.

Until then it would be enough just to provide some information (e.g.

That's a lovely animation. BTW the links behind "Info", "Recipe",
"Camera", i.e. the "View raw" stuff, don't work. (However the links
behind those little icons - the "View in forge" do work.)
