The next update will introduce an improved way of updating your Movies and TV Shows libraries.
Currently, any updates of the libraries run in the foreground and pretty much block everything else. That’s not a very nice way of doing it, so from version 1.8 everything will be going on the background. That way, you can do whatever you want while the libraries are updating and you can even browse your collections as they’re updating and look at the details of already added movies and shows. You could also take a look at trailers of upcoming movies or check out what’s hot on the most popular video sites.
You’ll find two screenshots of what it looks like in this post - the above one is for tablets and the below one is on phones.
