Q:  1.15.19  12:45 am have you considered disabling return to submit and then doing a simple trailing white space strip to get rid of all the enters at the end?
A: no, i actually found as a user myself, i became very frustrated that enter did not send it, especially for short submissions. and if the blank lines are there, that is proof that the user went through the same annoyance. probably more of an annoyance for them than it would have been for me reading it
