Simplify status pages / texts

[rvdsteege]

From user review on https://wordpress.org/support/topic/useful-but-quite-basic-still/:

Only downside so far is that you have to create status pages. it’s weird to me to have 6 different pages just for a short status text. And if the payment has failed, it might be better to send them back to the original location of the form, and put the status text there, maybe trough a post body or something besides the contact form.

I agree that it seems a little cumbersome to have separate pages and is less flexible than being able to set status texts per form. We might indeed be able to simplify / improve this.
