The only thing I would like to be able to do is to somehow only have the Page Settings visible underneath the page panel. The way it is now it is always visible in the left sidebar regardless of which panel is being displayed above it.
Normally, I would have the components displayed in the left sidebar, which does not need the page settings displayed below it.
Changed my first setup : Discovered the possibility to stack different sections vertically in a column: very useful application for working on a MacBook, for example. Optimal use of available space.
