Some ideas for very useful and helpful functions.

* Add a URL/Domain extractor.
With this function it should be possible to extract all URLs/domains from any text and save them to a file so that they can be easily checked at a later time without significant time and effort.
Simply a useful function for blacklist developers.

* Add a search function (yes I know you can do that with Linux, it would just be very handy to be able to do everything with one program).
With the search function it should be possible to search all URLs/domains with a given string in a file and save it to another file, and it should be possible to search multiple keywords by comma separation directly after each other.
This function is also very helpful for blacklist developers.
