Anything with a simple login form. It is completely user-configurable and shareable, like the new download system. It can do multi-page scripts, where it will parse some info from the first page and offer that as a temporary variable to another (like a POST form key or CSRF token). Anything needing a captcha is probably too complicated.
It determines login status with cookies atm. Cross-domain woo woo like exhentai is probably too complicated, but hydrus also supports importing cookies.txt from your browser so you can just copy across otherwise.
Today's release will be pretty empty, but I'll roll out some scripts for the big sites in coming weeks.
