@lilbud I see, I see, so you'd like to create a layout like this and keep the selection in the middle area: https://snag.gy/CGAw4Q.jpg
Looking at the video though, it seems the Switch UI is not actually a carousel. See there are two kinds of this linear layout in Pegasus:
ListView is easier to use but doesn't loop like a carousel (ie. you jump to the beginning/end on the last/first element). This is what the Switch UI uses in the video.
PathView is somewhat more complex but loops like the ES systems view. That's what the Carousel object in the theme uses under the hood.
So in case you'd like to make it exactly like the Switch you could take a look on ListViews too.
For both of them, you can use preferredHighlightBegin and -End to set the range where you want to keep the selection. The actual value depends on the type of the layout:
For ListView, they are in pixels, and mean the left and right edge of the area (like on the image above)
For PathViews, they are in percentage of the whole path, and mean the center point of the leftmost and rightmost item (maybe this animation helps)
