if I'm understanding what you want correctly this is already in StoreFeeder. If you go to the product page you will see a listing tab. This tab will show you all the channels where its listed and allow you to update the prices and oversell
We are aware that a lot of customers want extra permissions so it’s something we are very conscious of. In V2 of storefeeder we’re limited with permissions and so we can only make things “admin” only at the moment and if you contact support we can enable some admin only permission that locks non admins from doing product, listing and order exports and stops non admins from deleting orders.
We are looking into expanding permissions for V3 but as of yet we’ve not decided on how we’re going to be doing permissions as it’s going to need some serious thought from the team!

What information would you want restricting on the dashboard?
You can stop an individual user from seeing the dashboard at all in the Settings>Company>Users tab, clicking on the edit user link and the unticking the 'Dashboard' button on the 'User Permissions' tab.
