I've used this a couple of times now. It's very handy (pat on the back to John) and flexible.

I saw this last night as I fired up Miro. Looks very nice, but I haven't dug around too deep yet. Previewing the videos is a great idea so I'm looking forward to trying that out. Nice job.

I find these a great tool in Visio. I grabbed Garrett Dimon's templates and they have a great annotaion shape [ http://v1.garrettdimon.com/resources/templates-st...].
