_Story:_ Besides searching for keywords like variables or unique words in codes, one also sometimes just want to search for special symbols like "\t" or "\n" for some reasons. One would activate "regular expression" for this, but still, "\n" will not be found, unless "multi-line matching" is activated.
_Suggesting:_ To have an extra option for **multi-line matching** is somehow useless, this **should** obviously **be the default if searching for regular expression**. This also would simplify the search/replace dialog a bit.
