I am trying to determine which customizations to the ArcGIS Pro UI are global (will stick across all projects) and which ones are non-global (project-specific). I am making the assumption that within the Project Tab > Options section, the "Project" items would be non-global, while everything under the "Application" portion would be global settings. Can anyone (1) Confirm my assumptions are true, and (2) provide any more information about this topic? I have researched this question and found very little information within the help documentation.
I have been told that sometimes global changes only work for new projects created after the customization was made and are not honored in projects opened after, but created before. Why would that be?
