The option to add save or update a password after a successful login just seems to flash so quickly, it's hard to catch it - Fedora/Fx. The icons in the browser extension - why is a key icon for 'copy'? Why is 'edit' all the way at the top in the same colour/font as body text?
It seems to be the best of the bunch when it comes to password managers but I do find the UI a pain.
