I like the previous search result of the "File Content Search" where the searched value is highlighted/bold red and easily seen. I suggest to provide the same feature for the new ui/ fresh theme with the ability to expand all files in the result rather than expanding each files to identify the correct file to edit. Easier to select actions on the previous UI since buttons are visible rather than selecting the menu.
On click of edit - the placement of the File Editor is at the bottom, you have to drag it up to see it.
And the file is not rendered/opened in the file editor
For reference (previous Search Content result):
