I think it would be amazing if Wix created a non-browser based editor. If they created a software that you could download to your computer, harnessing the power of your respective PCs, and allowing offline editing capabilities, it would be a huge game changer. I love Wix, don't get me wrong, I brag about it all the time. The only thing that frustrates me at times is how the editor feels a little laggy, or that it sometimes gives me trouble when I am aligning different components. I'm not a web coding/performance expert at all, but my assumption is that it feels this way because it is limited by the resources due to it being a web based platform.
