Hey I wanna ask , why don't we get those chat bubbles with facebook messenger ? Is it because of the lack of support or it's because of a missing API ?? I'm asking this out of curiosity , and might win10 support this kind of thing ?
Pinning individual chats to the home screen would be an equivalent on WP, but I don't think that's supported as of now.
I honestly don't see the point of them, anyways. It literally saves you 1 click.
It's useful when reading something and chat about it , instead of jumping between apps
