A few features request - Xpath,view,key shotcut.

I have used Newsfox for nearly a year. I really like this add-on. Now I have 250 feeds to read everyday. So I request A few features for better use Newsfox.

1.
After I update Newsfox to 1.0.2. I found a new fuction, "filtered web pages". Is good for the feed which does not export full contents. I have read the description and example pages. But it's difficult for me to understand, because I don't know JavaScript. Can Newsfox add XPath support? Like a greasemonkey script "google reader full feed changer" ("http://userscripts.org/scripts/show/19949")

2.
Some feeds each article are short, such as a joke or a picture. So I prefer to read all new article in one page. Just like Google reader's "expanded view".

3.
My feeds list is too long, I need to scroll the mouse many time to locate the feed. Can add a funtion only display the feed which have news article?

4.
Search option dialog windows. I prefer to the force on the "search text" field by default. And auto copy the text in "search text" to "name" field. in other words, auto set search feed's name by default.

5.
Add a Key shortcut to run Newsfox.

Finally, thank you for your great work.

Greetings
