'Submit' Button to replace sign off tab

Hello community,

We have some non-power users that we are hoping to simplify form submission for. I had the idea of either a cui or form button that runs an action that bundles the "vote now" from the sign off with setting the default path and completing the vote. Has anyone done something like this?

The other thought I had was to just set the first workflow activity as the responsibility of the next owner however so that after initially adding the form, the item would essentially just be submitted on clicking done.

Thoughts? Any other implementation ideas?
