Feature requests

Thought it important to think hard about what features I’d like available in WordPress, as feedback is good and here are my ideas:

• Adobe viewer embedded in the content area of WordPress. Click on a pdf file link and the viewer appears with toolbar & close function.
• Searchable FAQ. Bit like programs where you are stuck on something. This would answer specific questions without reams of text
• The ability to mass email all/select registered users on your blog with news via the ‘write post’ screen. Handy if you want to invite members back to see a new updated blog. Maybe password protect this feature

Let me know if there are already plugins for this
