For training documentation my colleagues still prefer to waste a lot of time with creating presentation slides, which nobody keeps track of later on. Wiki has a lot of advantages to establish single source up to date training documents. But graphical features are poor. If we could use layered graphical content, an import feature from PowerPoint should not be a big thing.
Meanwhile an import function could make a pdf of each slide and embed it as a single picture to a single article.
Is there something like this already?
