I've been trying out different fonts on the K4. I can say Georgia looks awful! It doesn't render right. I don't like the original Caecilia, It's too wide. I prefer the condensed version but can't get my hands on it to modify it.
Right now I have settled on Tahoma which I use on my phone to read books. I love this font. It's black but thin not fat but still very readable. It's a sans-serif font though. I am using the Medium line setting. I've yet to find a condensed serif font I can use.
One thing I notice with the font plugin is that when you change the font sizes via the menu it kicks you out of the book and gives an error and wont let you back in. You have to go to another book then another till one loads then you can go back into your book and see the changes.
