Front-End Vendor Add On

I need an add-on that makes the Vendor panel less intimidating. I am considering two options:

1) An add-on that lets vendors make all their edits from the front-end.

2) An add-on, that let's me modify what shows up in the back-end for vendors. For example, when a vendor wants to add a new product, I simply want them to have access to the general, options, variation, and features tabs. My company will be responsible for handling the SEO. Vendors will not

offer quantity discounts or reward points and so they do not need access to these tabs. I want there page to be less cluttered.

Any thoughts??
