After testing the 3.9 beta version followed by RC-1 and RC-2, last minute hassles with the TinyMCE Advanced plug-in were overcome and all went well. The loss of image-editing features like easily added margins was a big disappointment and has already cost me many hours of extra work until I get used to having to do the styling manually. Why? I thought that certain frequently needed functions were incorporated into the core so we don't have to waste time or resort to plug-ins. This is a step in the opposite direction. I agree with Karelle, but will stick with 3.9, hoping that something will be done about this in the future.
