Want to edit layout mode, specifically, I would like to have the option to hide the left-side “groups” panel, which takes up a lot of real estate. I want to hide the entire left panel including “Sync Configuration” and ALL items (All References, Recently Added, Unfiled, My Groups, Find Full Text, etc.) from my layout. X9 had a layout button that allowed changing the layout mode, but I not available in EN 20. Please add this feature.
