Ah, interesting! If I recall correctly I've only pasted a URL in. I once knew HTML... Now that you mention it, I think I may have used a hyphen and a greater than sign to denote signal flow in a builder's note. When I get a chance I'll go try some things and report back. Thanks for the info!
And most welcome--it's a very useful resource for ideas and planning. Recently I tried reorganizing my rack on the fly without MG, and it took far longer with more furrowed brows!
