So I get that FAB is kind of new and it needs time to get better, but I truly hate how the connection to the launcher works. Maybe I’m doing things wrong, maybe it’s a me problem?
So what is FAB? It’s like a store that should seamlessly work with the engine? It does this very badly.
I find my self having to do tons of annoying window hopping just to add some stuff to my project.
Usually I look up what I have in my library on the website and hopefully find the thing that I need but then I can’t just add it from there. I need the launcher to add it for me, so I press the freaking “View in Launcher” button, that should, by all conceivable levels of logic show me that item in the launcher. But it doesn’t!!! 
I have to remember what the pack is called and search for it again inside the launcher to then add it!? Ever heard of UX?
Now I tried the FAB plugin thinking: “Aha! I’ve been doing this wrong the whole time”. But that’s just the same thing as the website, it just opens the launcher.
Is the website incapable of passing the ID of the thing to the launcher so it can at least show me the pack? It should be possible.
PLEASE make this work better!
** Edit So it looks like the FAB plugin does add packages to your project. In the case of this particular package it is a project and can’t be added in that way. So I was wrong on that front. Still the website and launcher connection is broken.
