Create a "Project Tree" feature that allows users to select a feature layer within a geodatabase and see the .aprx and .mxd files that use that feature layer.
This could make "house cleaning" geodatabases far easier so that you can anticipate what projects would "break" and fix them beforehand.
This has been marked by Kory Kramer as a Duplicate of Showing which .mxd(s) a shapefile, feature class, table or imagery is used. Though submitted specifically referencing mxds, if considered for implementation it would apply to ArcGIS Pro aprx documents.
This is an EXCELLENT idea!
I use "master databases" often and sometimes it's hard to know how projects are put together without spending some time right-click and checking data-sources.
As an added feature it would be a nice to be able to see what data drives symbology, labels, and even which features contain definition queries. This would help avoid the moments where we have to look at a layout or a map and ask ourselves how the heck we put something together.
