Hi Pierre,
After an hiatus for travel, I have been playing with the tabs-on-top version of MP from 6/22. Eventually the browser preview disappeared and could not be displayed. I had to restore a backup INI to re-enable it.
There appear to be several other behavior inconsistencies exacerbated by the tabs-on-top GUI schema. Is this new approach the one you will use going forward (I hope so)?
If you plan to continue with tabs-on-top in the MP development road-map, I can probably be more specific about the issues I have encountered.
