With regards anchors, it’s not something I’d typically use as I don’t think I’ve ever created a single page site. Having said that, it would be handy if I did.
Perhaps in the links setting window there could be another option for “Anchors”
Containers could have a property of Anchor which could be toggled on as needed. This way people could use these containers as anchor points and they’d be available as a link from any page in the site. Normal containers wouldn’t show in the list of anchor links - only those specifically toggled on.
With regards flowing columns of text, I’ve never used it (and our main massive Wordpress site was for newspapers) but that’s not to say other people may not need it. I agree with @bryanrieger about screen sizes and consistency of layout and design - I think it would be a nightmare to manage given the variance from tiny phones to massive 32" screens. That doesn’t even consider people’s typeface and text size options.
I was going to spend some time today on the beta but now think I’ll wait until the new beta drops - looks very interesting and it seems like the ducks are starting to get in rows now.
