In 1.7 you split out a lot of the CSS into separate files, it would be handy if you separated out the enhanced UI styles as well. Not only would it make updating them easier in the future but they would only need to be loaded if required.
It would also allow those wanting to update chosen to a newer version to use a function in their own theme to de-register gravity's bundled script and css and then enqueue the updated files from their own theme folder or cdn.
While you separated the datepicker styles out it appears they are still loaded regardless of whether a datepicker is in use or not so it may also an idea to change this so it is only loaded if required.
Thanks guys.
