I requested some sort of syntax highlighting for the search box, but it
wasn't possible due to limitations of Qt.
When modifying very convoluted search queries, is there someplace I can put it in and test whether there's no mistakes with the syntax and hopefully point out where I missed a bracket or something? Lots of "crap, why did it turn red?" after modifying a saved search.

Even more difficult when the search is four-five times the length of the input box.
