for teams dealing with many projects, it would make sense adding a new field “Project ID”. Which would be an Unique identifier for each project. This has the advantage to refer to a project easily.
Ideally this ID could be (for my company ) YEAR_OF_CREATION + Incremental number (f.eg: 2020001, 2020002, 2020003, … 2021001, 2021002,…) but with an incremental number would already fit.
Of course, the easiest option would be, to use the existing Database Internal ProjectID field, and let it visible (as read only) in the Project form.
