This is really awesome. Just one suggestion as a final improvement: Is it possible to get rid of the double suffix? At the moment the excerpt presentation is named, e.g., "TestPresentation.pptx s_2_5_9.pptx" and it would be great to delete the .pptx in the middle of the name. I thought about deleting the last five letters of the old name, but it isn't a good idea in case one has to work with a very old presentation, which is .ppt (only 4). Is there any other wy to come to something like "TestPresentation s_2_5_9.pptx"?


(Different topic: For those who wonder about the order of the numbers in the name: It seems to me that it depends on your clicks and turns the order from last to first clicked. So when I first choose slide 22, then slide 6, then slide 18, I get "TestPresentation.pptx s_18_6_22.pptx". Means: One can have a correct order - depends on his clicks. And we only talk about the order in the name. The order in the excerpt presentation itself is correct. Awesome.)
