[Plugin: Gravity Forms – Update Post] Suggest Corrections using this plugin?

Feature Request:

1.Is it possible that any logged in user can suggest a edit
After suggesting the edit, the post still remains published with its old content & if the admin accepts the edits suggested by the user than those changes are pushed to the post.

2. I am creating a recipe site, so it possible that any logged in user could submit a photo of the recipe?

Bugs:

1. Category is not loaded into a multi-select element.

2. Tag is not loaded into a single line element.

3. Image field is also empty

Great Plugin!!! Saved a lot of troubles!!!!!!!!
