I am developing a tool for launching scripts that do things similar to actions performed by bookmarklets via natural language commands. I am looking for use cases to develop scripts for that would get people interested in using this tool. I am interested in RFIs for bookmarklets because most can be adapted into actions launched via command.

To give an idea of the type of thing I am looking for, these are some commands I've already implemented:

* "search revisions for X" on a Wikipedia article will search the article's revisions for the given phrase.

* "measure speed" on a YouTube dash cam video will try to measure the vehicles speed based on the frequency median lines go by.

* "plot locations" extracts locations mentioned on a webpage and plots them on a map.
