Request: More intuitive default file selection in results
When having a file models/note.rb and models/note_type.rb, then typing note should select note.rb by default, not note_type.rb!
I guess this has something to do with the underscore _ coming before the . in the alphabet, but it's counterintuitive.

Good point. I often type a period at the end of my search to select the shortest filename, but it would be more useful if it appeared at the top of results.
I guess quite a good recipe would be to simply select the shortest available path in the list, this would most likely be the needed feature most of the times.
This is also a common unwanted case

I think space delimited searches should tried to be matched into slash delimited parts of the path (or whatever has been defined in "Space searches for").
