I believe that often, search results need more horizontal space to be truly useful than the sidebar allows, unless you expand the sidebar very wide (which then means less room for open files, and requires you to manually resize it bigger and smaller when going between search and editing, if you like to have the file tree open when editing).

My suggestion would be that search should have the option to display the results in a new tab, in a similar way to Atom or Sublime, or alternatively, the search pane could be relocatable to the bottom of the screen, so it would gain horizontal space in exchange for vertical.
