At the moment I miss only one thing:
boolean text-search in files (Google-like AND, NOT, OR).
I know I can use regexp. f.e. (cat.+mouse)|(mouse.+cat) to search for two words (even within several lines via additional lines box in cutomize). But how to do NOT searches, f.e. find cat but not mouse, how to find cat AND mouse AND cheese etc.?
The search result could then display every line containing one of the words.
