constantly hitting the send key, before im ready to send or enter the text

i can't begin to estimate how many times I've accidentally hit the enter key and ended up sending incomplete sentences, because the enter key is right below the delete key, so every time i have to backspace there's a risk of accidently sending the text. you guys have to fix it, please give us more theme options, that has all other keys in the default layout but puts the enter key somewhere else, or even just add a option to require a prompt before entering the text, that way if i accidently hit the enter key, a prompt will come up, tap outside the box to cancel it out. I've already been looking for a alternative keyboard. because i can't take much more of this awful placement of the enter key
