I am looking for software to make slideshows/presentations on CentOS, incorporating photos, videos and text (possibly also music) allowing for transition effects etc. I'd like to be able to drag and drop/rearrange photos etc. from different folders into a timeline and eventually end up with something I can show. Ideally without having to make copies of photos and store them in a folder specific for this but drag and drop from whatever folder the photo etc. already exists in. Impress and similar PowerPoint-like software excluded. I have found a few packages on the net but nothing that is still being developed. Does anyone have any suggestions? Thank you.
