It's really useful for me as I have two different Etsy stores and this is the easiest way to be logged into both rather than having to log out and in all the time. Among other purposes. The main issue I have is that I would really like to be able to use my own images for the icons and there doesn't seem to be a way to do that. It's a minor issue but as someone who likes to customise everything to the hilt it's just one of those things that bothers me whenever I switch profiles.
