We're currently trialing a new folder screen on the beta server. To try it out, just login at http://www.fastmail.fm/beta/, and click on the (Edit/Refresh) link at the top of the folder list on the left hand side of the mailbox screen.

The new folder screen is designed to solve a number of issues.

  1. Creating a new folder is now quick, easy and intuitive with the
    section at the top of the screen
  2. Creating sub-folders is also much easier, rather than having to use
    a name like parentfolder.subfolder1.newfolder to create a nested
    folder, you just select the folder name you want the folder to be a
    subfolder of
  3. The folder list is now sorted and displayed in exactly the same
    order as the folder list on the mailbox screen, making finding
    folders much easier
  4. Moving folders and renaming folders is now much clearer and straight

In an effort to allow more options on folders in the future as well (eg. we'd like to add the ability to set folders to auto-delete messages older than a certain time), we've moved the setting of options on folders to a separate screen, rather than having one big grid. When setting the options on multiple folders, we've tried to follow the iTunes approach which uses checkboxes to control exactly options you want to set.
