I looked up a Twitter demo of how the new floating window feature is going to be used [0] and my only reaction is "I hope this doesn't get used by any core feature of the editor in the future". There's something about an always moving visual element that isn't directly under my control that feels extremely uncomfortable to me and is something I honestly didn't expect in vim. One of my favorite things about it has always been that it took up about two columns and a row of space to display anything that wasn't the file being edited.
