Permission on column level
Fine grained permissions on column level (View, readonly, edit ...)
Star D. commented
We've created documents where one audience needs to fill out the top portion, but the bottom is for another group (e.g. security, HR, etc). While we can hide those columns in a view, that won't keep users from accidentally changing those fields in the details/properties.
This is often even more problematic because often those field values trigger workflows.
If we had the ability to control column access via permissions, we wouldn't have to worry about people "staying in their lane".
This will be helpful to avoid form customization using SharePoint designer
You can use custom-built views for this - just a thought.

Very helpful, could be for manager comments, etc.
