Introduce an option for collapsed mixer sections in Loopy Pro to stack horizontally rather than vertically. This would maintain a consistent and intuitive layout when collapsing sections, especially when resizing the mixer window or widget page.

Currently, when collapsing mixer sections, they automatically stack vertically, which can be disorienting, especially if the mixer window and widget page rescale simultaneously. This behavior can make the layout feel cluttered or unpredictable, particularly when only a few elements are present. Maintaining horizontal alignment would preserve the spatial relationship between collapsed sections.

Add an option to switch between vertical and horizontal stacking for collapsed mixer sections. When enabled, collapsed sections would align horizontally, maintaining a minimal height and consistent layout, even when resizing the mixer window. This would reduce visual disruption and improve usability.
