How do I move the search filter sidebar on inventory list page?

Answer:

Once you open the Remora Administrative Portal and select Inventory Settings under the Inventory Mods tab (look at how to access inventory settings), click on List Page (pictured below) in the blue navigation bar at the top of the page.

Next to Filter Sidebar Orientation, there is an Orientation drop-down menu (previewed below) with the option to select Left or Right.
