Penguin Mail 0.1.6

Fixed

• A message the assistant writes puts your signature under the words,
  not above them, with a blank line before it.
• A message that sets no colours of its own is drawn in the window's
  colours instead of on a white sheet, which in a dark window meant a
  bright slab. Mail that picks its own colours, such as a newsletter,
  keeps its white page.

Improved

• The composer's header has room for its title again: Sign and Encrypt
  sit behind one button that says what the message goes out as.
• A message in a conversation slides open and shut instead of appearing
  all at once, and mailbox rows, conversation rows and attachments fade
  under the pointer. Turning off animations in the desktop settings turns
  all of it off.

New

• Unsubscribe fills in and sends a newsletter's own unsubscribe page,
  after you confirm what it will press. A page it cannot read still opens
  in your browser, and a newsletter that hides its way out in a link at
  the foot of the message now has an Unsubscribe button too.
• Right-click a message inside an open conversation for a menu that acts
  on that message alone: reply to it, archive it, trash it, mark it,
  flag it in a colour, label it, export it, or copy its sender's address.
  Archiving one message of five leaves the other four in the inbox, and
  Ctrl+Z takes it back. The Menu key and Shift+F10 open the same menu for
  the message you are on.
• Ask the assistant to unsubscribe you from several newsletters at once.
  It lists the ones you get first, and asks about all of them together.
• The assistant can send a message waiting in Send Later or the Outbox
  now, cancel it, give it a new time, or delete it from the Outbox.
• The assistant lists your reminders and can move or cancel one.
• The assistant can unmute mail, read your muted mail and smart
  mailboxes, and undo your last change, as Ctrl+Z does.
• The assistant can rename, recolour and delete labels, change and delete
  smart mailboxes, and save and delete templates. Before deleting a label
  it tells you how many conversations carry it.
• The assistant can add people to your Google contacts and change the ones
  there, after asking.
• The assistant can let a sender's remote images load, or stop them, and
  tell you whose images load now.
• The assistant can export conversations as an mbox file, or one message
  as an .eml file, to your Downloads folder or a place you name. It never
  replaces a file without saying so first.
• The assistant can forward a message, add a Bcc, attach files from your
  mail or from this computer, and sign or encrypt what it sends. It asks
  before it reads a file from this computer, and names the path.
• The assistant lists your drafts, and changes or deletes one when you
  ask, encrypted drafts included.

Fixed

• Cancel Send keeps a message you scheduled while offline. It goes to
  Drafts, or, while Gmail is still out of reach, opens in a composer for
  you to save.
