I would love to expand a crate by clicking on the arrow without the focus of library shifting to that crate.

Many times I highlight tracks via a search within that crate that I want to put into a subcrate of parent that isn't expanded. When I click to expand, I loose my search results as the library focus shifts. You should be able to expand the crate by clicking on the arrow, but the focus shouldn't shift unless you click on the crate itself.
