Would it be possible to have more options on which panes to stack, so that I can have a preview pane above the catalog? I only need a small rectangle as preview pane most of the time, and I have vertical screen space left in the catalog.
The ideal situation would be that all panes are dockable like in Visual Studio or Android Studio, so that you can stack or float them at will, above or next to each other, or in tabs, or floating on another monitor - but that might be more ambitious than just a few additional stacking options...
