Some questions, some answers.
If you are pleased with how the original admin interface looks, you shouldn’t.
see Troubleshooting.
We are testing with Firefox, Chrome and Safari. IE9 and Opera should work fine as well.
Of course.
Unfortunately, Redactor currently produces strange/wrong HTML. Moreover, we’re missing an easy way to define formatting–options as well as a possibility to insert classes. That being said, TinyMCE will be removed with version 2.5 of Grappelli. Instead, we will add a skin for TinyMCE.
For now, custom Compass-based stylesheets gives us much more options. But we do understand the need to easily customize the admin interface and we’re discussing this issue on a regular basis.
Occasionally, we discuss features and implementations.
Help is very much appreciated.
Our goal is that Grappelli will be redundant eventually (though we doubt that will happen).
