Emphasize "commenting as", especially on alts

[jewel-andraia]

It would be nice to highlight which username you're commenting as. This would especially be good when using an alt account (which should be an option, enabled by default). I would define "alt account" as "not the first username on the account switcher options" for simplicity.
