Indexer 1.1b1 was released today. This update makes it possible to protect specific folders from anonymous viewing via a password. To prevent a user from having to re-enter their password every time they change pages in a protected directory, Indexer now uses a PHP session to keep track of the user’s viewing permissions.
I am aware of the rendering bug with the <fieldset> tag for public file uploading and will be fixing it in the near future.
