Meet Stanley, an admin theme inspired by rubik
I like Rubik as an admin theme (for clients) for Drupal projects. But now there is a new admin theme available called Stanley which is inspired by Rubik but uses bootstrap (by Twitter) for its UX toolkit. I took it out for a spin and I kinda like it! It's clean, clear and fast. Also, the theme is optimized to work well with popular modules. For example, context doesn't give you double scrollbars anymore!
