When I started coding against API a few months ago it seemed to be a lot less complete than it is now.
Sometimes documentation has been added ahead of availability of the function.
Is there a current list of available features?
I am particularly interested in list=search, action=login and (most of all) editing via the API.
Currently my code is editing via html forms and scraping the result, which is less than ideal.
Last time I tried API login it returned a cookie which was rejected by the site when I tried to use it for editing, so I still use the screen scraping technique for login.
Last time I tried search it didn't work.
