I am the production department for a medium-sized publisher and need CSS style sheets to survive.  We just upgraded from CS5 to CS6 and I've found that CS6 is practically unusable for epubs!  What is going on Adobe??? I appreciate you are trying to make it easier for individuals to make unique books, but you have royally screwed larger production departments that use series CSS sheets to pump out books.

1.) What has happened to the list feature?  I used to be able to "apply bullets" and use a paragraph style and things would map beautifully to Unordered Lists.  Now there are extra bullets applied.

2.) Despite the fact that I have "Keep Overrides" unchecked and use an external style sheet, there are character overrides being applied and they are uniquely named for each one!  There's no way to globally fix this without hours of extra work!

3.) Each image is being renamed with a unique div class.  So there goes my ability to fomat pictures globally with my tried and true CSS. 

4.) As mentioned above, the capitalization conversion to lowercase disappeared for paragraph styles, but for some unknown reason is maintained in character and object styles. Why the unnecessary change?

This is a MAJOR headache and I will go back to using CS5 as CS6 is unusable for large scale production. It's fine to move forward with individuals creating books on a small scale, but why delete the options that made those of us creating on a large scale to use our own CSS?

Please, please, please, please, make a bug fix that allows you to completely bypass the InDesign CSS and attach your own as there was in CS5. This renaming is a version killer and I won't recommend it to anyone.
