After a lot of trial and error I finally figured out how to make a glassed version of the Feedr widget. I'll post it here if anyone's interested. I used metamorph to install it, done the same way as tekhawk described in his helixmod. Put the attached glassfeedr.zip in the androidthemes folder, move com.feedr.apk from data/app to system/app, apply theme in metamorph, reboot and the feedr widget should look like it does in the following screenshot. I might still try and work on it a little bit, maybe change the number in the upper right hand corner, but I'm happy for now because I've been trying to get this for a long time.
