Allows Skype contacts to be searched from within the applications overview. Clicking on a contact will launch a chat window. After install Skype will also pop-up a window to confirm that the extension is allowed to communicate with the Skype API. Latest version has a bug, which I hope to fix in the next day or so, until then if you don't see any contacts, try reloading the shell (Alt F2, then 'r' in the box that pops up).
Note: Binary files aren't shown on the web site. To see all files, please download the extension zipfile.
This is not what I meant. I meant using indexOf, rather than a regexp. I do not see the purpose of a regexp here, since you're not using any features of a regexp besides string matching, which can be done with indexOf.
