On my Galaxy Pro Tab 8.4 I can make floating resizable windows. But I don't like the way they minimize. My preference would be that minimizing a window puts a marker in notifications so that when you pull it down you can bring the window back up. Ideally if you were, say playing a video or streaming on youtube you would continue to hear the music when the app is minimized. That works for certain apps but not all. Looking forward to seeing what Jolla does.
