The new desktop overlay feature is pretty neat.. But I have noticed it gets annoying in the longer run and unfortunately disturbs work as it covers tools and features of the apps I use.
In any other apps, option to disable such features are completely obvious. But for some reason Spotify does not user control lot of things in the app.
EDIT: The new version now has an option to disable this window!
Hey folks we've implemented this for our Windows users. Thanks!
