Created attachment 52692 [details] Mockup of the slide show editor Version: svn (using KDE 4.5.2) OS: Linux Currently the custom slide show editor is a separate window with an entirely separate UI. However, in principle editing custom slide shows is not that different than organizing a single slide show, which is what the slide sorter is for. So rather than having a separate window with a separate UI, I think it would be better having the custom slide show editor being similar to the slide sorter and activated in same would way be bother more natural for users and easier to program and maintain (since the slide sorter and slide show editor would share a lot of code) I have attached a rough mockup of what I think this could look like. Reproducible: Always
