Until a few updates ago, Impress’ custom animations (basically, click-to-reveal) worked perfectly; now they’re broken. What I want is to be able to back up through a slide with click-to-reveal animations. The backups should go in reverse order of the original forward reveals, then I should be able to go forward again at any point. It is very common to need to back up a few clicks (someone asks a question, whatever), but it’s impossible to do now without the ordering of the custom animations becoming hopelessly scrambled. The only way out is to keep backing up till the previous slide is showing, then start over on the original slide.
What caused this breakage? Is there a setting that will fix it? Is there a practical workaround? Can it be fixed? (!!)
