I have LSmita.wordpress.com in the Twenty-Ten theme and it's okay, but a bit staid.
I really want to see how our blog would look in the new Adventure theme, but when I click preview on Adventure, it doesn't create a sidebar. Everything is full-width and that's not what I want. I don't see a way to customize the "test" to really see what it would look like when properly configured without fully activating the theme.
I have no problem doing the configuration but... if I don't like it, I don't want to have to then rebuild my blog to bring it BACK to where it is right now, working just fine. Everything just where I want it (in it's IKEA-like sterility).
Is there a way to more fully "test" a theme candidate and / or more easily "revert" my blog if I find a deal-breaker of an issue that makes me want to go back to the safety of the Twenty-Ten theme? I guess what I'm asking for is a "sandbox" where I can test different themes, configure them to work for me, and be able to leave my existing blog completely untouched. (being able to switch between two or more "candidates" would be just amazing."
The blog I need help with is lsmiata.wordpress.com.
