Improve the usability of the mixer toggle controls in Loopy Pro by placing both the open and expand controls on the same side of the interface. This would make finding and pressing the controls more intuitive and consistent.

Currently, the control for opening the mixer is located at the bottom left, while the control for expanding the mixer appears in the middle right. This inconsistency forces users to search for the button every time they switch between views, interrupting the workflow.

Move the mixer expand control to the same side as the mixer open control (bottom left), ensuring that both actions are accessible from a single, consistent location. This would streamline interaction and reduce user confusion when toggling mixer views.
