I have a beautiful theme which says it supports 1.4.x. I want to use it in 1.6. Is that possible? How well does 1.6 support 1.4 themes?
You would have to revert several templates in a 1.4 theme to make the 1.6 features appear.
+ add all the new classes to the CSS
It's not recommended to use a 1.4 theme on 1.6
