The line number is displayed.
Okay, besides the line number, I’d prefer the whole line, which contains the matched string, be displayed. This would give you an additional information on match (without a need of jumping between line just for seeing the line contents).
Hopefully I’ve explained myself with my pure English experience.
As for me, I’d just replace the file name in the Search results window with the line contents.
What do you think about changes in this plugin?
