Gordita: Reader has one-click starring and sharing of items, but you may want to do the same to pages outside of Reader. Gordita lets you create a bookmarklet that allows you to copy Reader items that interest you to del.icio.us, along with all the other items you’ve bookmarked over the Web.
Google Reader Optimized: This set of user styles maximizes the reading area. When you want to sit down and power through hundreds of items, you may find this compact, stripped-down interface preferable.
Controlling Google Reader with a Cell Phone : This add-on may be a bit out there, but in a nutshell it allows you to control Reader with your Bluetooth cellphone. Perhaps if used in combination with the full-screen style above, you can build your own Reader 10-foot user interface.
