I found out that you cannot use Themes if you don't use a custom layout?! I had a problem with formatting text in the new version of Marvin (Problem that I did not have with the old version), reverted to default publisher formatting and then could not use the Themes colors?
Finally by fiddling around I was able to correct the problem using my custom layout and thus could get the color again but that was uncalled for in my opinion. Anyway, it is still a great and probably the best reader out there!
And yes, textures, would be a great plus! Old paper for me too, please!

I just love a bit of skeuomorphism! (I just wanted to use that word!

Call me pedantic, I know...

)
