Change "send" to "schedule" in email scheduling modal box

This is a feature I use frequently, and this small verbiage change would help for clarity.

 

Instead of the blue "send", I think it should say "schedule".  I know it says schedule at the top in big letters - but every time I click that "send" button I second guess myself.

This was brought up the FB community before, so I know I am not the only one.  Thanks!
