I miss my Old theme, but the Babylon is close to its header layout which is what I liked, but a nice theme all the same.
I'm not sure I like the thumbnail views of attached images, no problem for those viewing them infrequently. But, a real pain for those helping having to open it for reference and each time you revisit that topic in the process of helping that user the image is in thumbnail format, again if need be you have to open it again. I guess we will have to see how it works out in the long term.
I didn't notice the forum 'Policy' button on the row of buttons, I like that being there as there is no excuse for not knowing the forum policy.
The Babylon theme also has the SMF logo.
