Placebo search button? Based on effect it doesn't seem to do anything, and visually it looks like it "sticks" and doesn't ever get "pressed" when you click on it.
Thanks for the feedback--I only search on property names (not descriptions or possible values), so that's why gradient doesn't work. It's a two-line change to add matching on values and descriptions, so I'll put it on the todo list of "advanced" search options.
also, it can't handle "gradient" at all.
