I would very much like to make use of regular expressions while searching through my library and configuring your so called 'smart lists'. Most of all I would like to make use of the dot '.' (any character except newline) in combination with the quantifiers '*', '+' and '?' (0 or more, 1 or more, 0 or 1) in order to circumvent having to make use of a ridiculous amount of OR statements. I look forward to any reactions on this feature request.
