The dirty secret with the ‘Open’ button in the Resource Library Quick Look view is that we intentionally disable it. Hype right now doesn’t like its files being modified from underneath it, which is what opening in another app would do. There’s no way to hide the Open button in the Quick Look view, so in adding the view the best I could do is disable its functionality. It’s really a temporary solution as it is a valid request to be able to edit assets in another app
