By dateIn old Caché versions it was possible to create a new role based on predefined %Developer by copying it and adding some resources as needed. It was true at least from 2010.1 to 2015.1.
After upgrade from 2015.1.4 to 2017.2.1 it turned that it's only partially true now. User with a "New-Developer" role can enter Studio and open existing cls/mac/etc for editing and everything is OK unless he tries to create something new (Ctrl-N), than he gets a pop-up with %msg: <User xxx does not have enough privilege to execute stored procedure %CSP.StudioTemplateMgr_Templates>
