I can say your top 2 is currently Wix’s top 2 as well. 
Some are not as high a priority for Wix as the others, but most are in the pipeline. I can tell you our Ecom is also a huge focus - and it’s clear because Wix is pumping out incredibly powerful features at a rapid pace.
As far as support… I have something I’m also working on for the community. Stay tuned.
