The scrollbar in the object selector in the ST app is not intuitive. Every time I open the Object selector window my first instinct is to tap and drag the left side to scroll through available objects. That, and the scrollbar doesn’t look like something I’d use to scroll with - it is too far to the right (doesn’t look like it’s associated with the objects list), and doesn’t contain any UI within it to imply I use it to scroll.
Thanks for bringing this up! It’s slightly more intuitive on the iPhone layout, but I definitely agree and we will use this feedback to iterate on the design
