Well I mostly use the app I mentioned, which has skip backward/forward functionality.
There's very few other apps I use with it (amongst those are Netflix and BBC iPlayer) but they function perfectly. I think the biggest factor on its success is wifi signal, I've never had anything but joy with it.
You can "cast" a Chrome browser tab or your mobile screen too with the Chromecast app, which works but not quite as well I've found (saying that, casting from a desktop/laptop browser tab seems much better than it was a few years ago - it was unwatchable but now I see very few drops).
