This makes me think of how Facebook removed the "Sumbit/Post Comment" button from comment forms. I'd argue it's not obvious that hitting enter will do the trick because enter is for starting a new thought on a new line. They've replaced the natural enter-for-newline with the shift-enter (even more un-intuitive). This has caused me no end of frustration as I accidentally submit unfinished comments and can't submit them at all on the numerous occasions when I repeatedly hit enter with no effect whatsoever. What was wrong with having a button there? Please can we have it back?
