In the Goto Anything dialog in build 2210, the selected file is indicated by a solid light grey fill (non-selected files are indicated by a solid dark grey fill).
When there are only two candidates/files to available, it is difficult to immediately tell which file is selected.
Suggestion 1: Change the selected file fill color to something obnoxious/obvious like blue, orange, red, green.
Suggestion 2: Append a suffix to the file "(Open in new tab)" indicating the action that will occur if the user presses the enter key.
