Simply disappointed
Owncloud itself is absolutely great tool. It is multi function with easy-to-install addons. You can build your own cloud leterally.
However this app is not compatible with various add-ons. All you can do is to watch/upload images or download/upload videos and files.
It is not compatible with video streaming, image previews, calendars, etc., etc.
Seriously, what ownCloud makes special is its extensibility, so please make app catch up with it.
