Hi,
I have two points regarding the search function.
In other applications I use, it’s possible to highlight a word and then press CMD-F to have that word automatically populated into the search field. This doesn't work in Xcode, and it’s really annoying.
Secondly, it bothers me that the two search fields—the one in the sidebar and the one above the editor window—are linked; specifically, when I clear one, the other disappears as well. They serve two different purposes and should remain separate.
