I see a lot of devs/codebases use $event instead of event - for whatever reason. Perhaps just to signify that it's a DOM interface?

Yeah, and pages rendering fast is the whole reason I'd love to be able to use grid layout, instead of the JS crud implementations we're stuck with. Just surprised, given how many wins everyone would seemingly get out of it - but I imagine it's also a very tricky implementation issue. A new layout model consistent across browsers has got to be a nightmare to develop.

I'm building a large, complex web app in Aurelia right now, with a .NET / Azure back-end. Going great so far! A little worried about the SEO implications of Google not being able to see Aurelia views correctly, but will cross that bridge when we get closer to production.
