While browsing the theme showcase I came across a very interesting theme called: "Annotum Base"
It is a very highly customizable theme but I am weary to use it because I know nothing about it and it gives you a warning at the top when you use it which leads me to think that maybe it isn't your average joe's blog type of theme.
WARNING! You are currently running an Annotum-enabled theme: Annotum Base
Switching to a non-Annotum-enabled theme would make your scholarly articles invisible, if you have any. Never fear, the content would be preserved, but can only be displayed within an Annotum-enabled theme. Should you want to want to switch to one of our standard or premium themes, you can convert your articles to standard posts beforehand. By doing so, your articles will be visible under any of our themes.
It can use widgets, you can customize the colour scheme but not set a background image. Just seems too good to be true, something that offers so much customization it has to have some catch right? Any info you can give would be great. Thanks! :D
