Weblog Desktop Software

Hi,

I am after a desktop blogging software that meets the following criteria:

• Manage multiple sites
• Post multiple images
• Set featured image
• Choose categories/tags
• Attach files (and show what is attached)
• Scheduling (a nice to have although ability to set default timestamp would suffice)
• Post and edit old posts
• Set status eg draft, publised
• Set custom fields

I have looked at a few like Windows live writer, Blogjet, Thingamablog, Blog Desk etc but none match the full criteria.

Any help appreciated.

Thanks
Mark
