There are a number of visual enhancements to PowerPoint 2013. Some I like, some not as much… One I really like is a small update to the slide sorter when reordering slides.
Now, when a group of slides are selected, they minimize to a small stack icon (here I have grouped 29 slides displayed as a single icon). This is a small update, but it makes it much easier to move large sets of slides and quickly see where the slides need to move to.
