Hi Juergen, I don't know if there is still any energy left on your side, but even short time work with outliner and beamer shows that the new system breaks one of the cool features we had - reorganizing slide order via outliner's buttons up/down :(
We can start with this one: 1. open beamer manual & outliner 2. go to the first frame 3. hit outliner "down" button. 4. 1&2nd slide merge together I have in my pockets example when only moving section down works, but not up. Playing with it for a while produces crash, it might take a while to produce MWE but I try to come with it within couple days. Pavel
