As I promised there will be more subscriptions, extensions and features. Now you can get the SchuWeb Gallery Pro extension which includes video service integration. You can add YouTube and Vimeo videos and display them like your images.
But there are still features missing, so it is a beta version. There will be tagging, so you can display videos and images under one tag. Different layouts and more enchanted display options for the videos.
The last feature depends highly on the number of subscriber, because it can be that I have to pay for some developer access.
So have fun with it and write your thinkings and wishes into the subscriber forum.
