Kovid wanted me to do the display of saved searches differently.
The first image is what you see if there aren't any saved searches in the expression:

The next one is what you see if there are (recognizable) saved searches in the expression:
The saved search text can be selected with the mouse and copied to the clipboard. You would do this if you want to convert the saved search reference to the associated search expression.
This code is in trunk for those of you who run from source.
