There are design information field data that can be restricted for some users. In this example, we show how one admin user can add/remove while one user can view the data, but not remove it.  This can be managed by custom dialogs management. You can create multiple dialogs for different categories.

In the case of the keyword data, the admin category would have one custom dialog setup to view and right the data, 

While the user category has a customer dialog setup that allows one to view the data, but read-only.

The result would be, that the admin can add/remove the information in the keyword,

but the user will be able to view it only and still be able to access the Edit design dialog.
