Hi Elisabeth

I have the same experience, and editors prefer the forms edit mode in about 99% of all cases. It is simply more effective to work that way (it is faster to load and gives a better overview). I believe the new visual builder might change this since it will have a bit of both. This, however, is still up to us when designing and implementing the page types and templates with or without the usual On-Page editor or Visual Builder. If things are complex, e.g. having logical switches in a page type to empower the editor there is really no place in an On-Page editor for that out of the box. We surely can expose such settings on the template (only visible when in edit mode), but usually don't. Maybe we should?

I agree. All properties is the most common and default view. I real life, On-Page editing is something that is replaced by the practice of:

1. Enter to a page type or block
2. Edit content in "All properties"
3. In edit mode open the page to verify content rendered correctly
4. Publish content if content verification is ok  

I agree that visual builder will introduce the new "experience" of pre-visualize content rendered at same time content is edited. But my concern is regarding limited "screen space" that makes all previsualization looks like mobile chanels. I suggested Optimizely to automatically hide the page-tree  and right pannel when editors are using Visual Builder, in order to gain more pre-visualization space.
