It would be cool if you can put an option on the admin>>>submitagain where, user can go there and simply check which content he want the submit again to appear on. this is very useful if user already have many content type, so he doesn't have to go to each individually to enable the feature.

But keep the ability to add submit again on the content type too. This will enable the user to easily add it when he create a new content type

Great module, it really save me so much time ;)
