There are two things I'd love to see Videostream do (that are probably way too much work to implement):
I'd love to be able to pause a video and zoom in on the scene and pan round a little. This is an effort to be able to read those phone screens that are increasingly popular in tv episodes and movies where the actor is sending/receiving texts.
I'd also like to be able to maybe pop up a screen that shows all the videos in my streamingvideo folder and let me use my remote-control/phone to select which four will show up in the GUI to be selected to play. The way I do it now is to go all the way to the other end of my house to delete the videos I've already watched and move four more into my streamingvideos folder. I would prefer to just dump all the videos I plan on watching into my streamingvideo folder and selecting the four that show in the GUI remotely.
On the whole though, awesome job with this app guys!!! :)
