Tim, I don’t know this to be true, but I suspect power users aren’t the target audience of Wix. I think they are selling boatloads of sites to DIY’ers. We just need to realize what our boundaries are with Wix and either work within them or switch to a different platform.
It honestly reminds me a bit of Apple. As a Mac Pro user you can just expect to be ignored by Apple since they’re more interested in selling a kajillion iphones than a handful of high end desktops.
Having said that…I’ve seen remarkable advances in the Wix platform over the years. Just the reality that there are power users who are building sites on the Wix platform was unheard of just a short time ago.
Also, don’t stop pushing Wix to develop features that you want.
