Webmail

• Set up thread view with a "quick reply all" textarea to reply to the message
• Set up thread view with a "quick reply" textarea to reply to the message
• Update the "Forward" action in the thread message dropdown to go to the full reply compose page
• Set up the "Reply-all" action in the thread message dropdown to go to the full reply compose page
• Set up the "Reply" action in the thread message dropdown to go to the full reply compose page
• Add a button in the quick reply form to go to the full reply compose page
• Display list of addresses in the To field in the quick reply-all form; exclude the current user's email from that list
• Set thread ID and message ID (uuid) on the new replies so that they show up in threads
• Update the draft mailbox to load the replies
• Include "Draft" message in the mailbox thread as a message if it exists
• Display an alert on the draft message within a thread that it's a draft, with a way to edit that message; otherwise, the edit form should be automatically enabled for these messages
• Update reply-all form to load data from outbox message if it exists
• Create a reply compose page that allows for updating the to (and other address fields)
• Set up reply compose page to display the previous message on the right , with a way to expand other messages in the thread
• Load the existing outbox draft message on all edit operations if it exists (no duplicate drafts) and redirect to compose page if the draft exists already
• Disallow two drafts within the same thread for now, too complex
• Load the existing outbox draft message on any attempt to reply/all to the same message
• Preview-and-Send from reply-all page redirects to /reply/ 404
• Disallow editing / message actions on draft message when in thread view
• Enable "cancel" links from the preview editor to prompt a confirm message and then delete the draft message and return to the thread
• Set up the outbox preview page to include a link to display the message/thread being replied to if it exists
• Update compose page to include a link to display the thread preview when replying
• Expand any draft messages in a thread view (only drafts in the last message are set to expand)
• Testing: create a mid-thread draft then go back to the thread and click the big reply button at the bottom and try to create an end-of-thread draft message. You should not be able to create a second draft but it could be a weird userflow.

Sending

• When saving the draft for a reply, store the parent_id message ID with the outbox message
• Update Send task to load the parent message when parent_id is set
• Add the References and In-Reply-To headers in the Send task when the parent message exists
• When creating the sent message, store the thread's thread_id so that it shows in the thread
• When creating the sent message, create a copy in the sent mail folder and the all mail folder
• Verify that the new messages display in the thread before sync (new message should have purge=1)
• Verify that the new messages display in the thread after sync (new message should be pulled from server)
• On sync, during cleanup, do not purge any purge=1 messages that have active jobs in the queue (prevents deleting messages if a message is sent, or queued, while there's an active sync/download running)
