What are you trying to accomplish?

• administration -> projects -> project attributes index
  • add "all projects" indicator
• administration -> projects -> project attributes edit
  • show correct caption in "Projects" tab
  • hide "add project" button
• projects -> project attributes index
  • control toggle box via for_all
  • show "all projects" indicator
• administration -> projects -> project attributes -> new (multiple flavors)
  • add is_for_all checkbox
• double check API
  • check projects API
  • check custom fields API
• Project Initiation Request -> for_all fields can be disabled
• Project Initiation Request -> Toggling is erratic when clicking "enable all" or "disable all"
• Project Initiation Request -> ensure only configured attributes show up in the creation wizard
• migration: set all fields which are currently is_required=true to also have is_for_all=true
  • Warn DevOps, usually there are no migrations allowed after feature freeze
