Inside the table of contents there's an under utilised tab, the List by Source tab. The reason, I feel, it is under utilised is because you can't do a lot with it, other than see the sources of your data. There's no real control or editing to be done here.
I think it'd be great if you could right click on a datasource and choose 'repoint source'. Often in production environments you load data first into a replica working geodatabase, being able to quickly swap this to the production database would be fantastic.
If it was smart enough to match the layers that are in both and leave, unchanged, non-matching layers, that would be great too.
It would also be great to 'export list of layers and sources to file' - essentially exposing this function: https://support.esri.com/en/technical-article/000011530 but allowing the user to save a table or text file.
