FAB in Launcher, is it working for you?

Hello everyone. I just made a deep dive into the FAB in Launcher, really trying to figure out the ins and outs of publishing. Lots of trial and error. What do you think? I made a YouTube video about it here:

If anyone has any thoughts and feedback for this I would be very happy. I got some things to work but a lot of things didnt come out right. Maybe I’m doing it wrong or missunderstood the document. You can comment on the youtube video as well I read all the comments there.

I really want the FAB experience to be as smooth as possible for the user.

Thanks
