Add the ability to post using standard and multi-markdown.

Would it be great if you could create a new post in PostWarden from the menu bar, select a time in the future, and then have PostWarden upload that post for you at the scheduled time?

Would it be great if you could queue posts even if you're offline, and the have PostWarden process that queue when your back online?

For example: find all “happy” tags and replace with “yay!”.

Browsing the archived posts is a great way to discover old posts which one might like to share again. It'd be nice to be able to reblog those old gems directly from PostWarden.

To search by tags and content

It'd be nice to have a formatting bar (including bold, italics, strike throughs, links, quote, and bullet points, etc) for those of us that don't know html. It'd make using PW so much easier.

Being able to hit tab to switch between fields (for example, between "body" and "tags"). Using 'return' to confirm the clearing of fields or deleting posts. Using arrow keys to select between months in the archives.

Have a button to publish drafts directly from the PW window without having to go through the composer to edit and publish.

PostWarden archives all your posts and stores them in YAML (which can be easily used by developers to do neat stuff). Wouldn't it be great to export all the posts into HTML ready to be used?
