Change the fields that are available in the gf backend editor

Hi everyone,

Are there any hooks available to hide settings on fields in the backend. For example how to hide the populate field on the advanced tab or the custom css field on the appearance tab?

OR maybe there is a hook to hide complete fields from the backend user? Like for example if I don’t want the html field to be available for a certain user or maybe hide the complete post fields panel?

The reason I am looking for this is because I have a customer that finds the backend too complicated for their needs. I know I can remove all that I want to remove with javascript but I was wondering if it could be done through php as that would be better of course…?

Thanks in advance. Happy new year to all that read this.

Kind regards, Johan
