#ERPNext_Buttons_Permissions_control
So what if the management wants to fully control the permissions on several core ERPNext buttons like : [ Duplicate - Links - Reload - etc …] 
For example what if they want to prevent a user X from pressing the “Duplicate” button to create a new sales order, since making a document with the duplicate button could cause some data issues
I made a small feature to solve this thing, I removed 2 buttons from this user in the video and re-enabled them again.
With This feature you just need to choose the user you want to control , doctype , and which button you need to hide
