Here are two extra patches I use on my Glo, for firmware 3.1.1 (761b066420):

A replacement for the standard line spacing patch which is a little more complicated to configure but allows an extra 4 values on the line spacing slider;

and a patch to prevent the AndroidBookLoadTablet_Aspect.parsed cover image file being downloaded or generated, which fixes a problem with the cover image for kepubs not being displayed on the book details screen if wifi is turned off.
