BTW, have you tried consult-org-agenda? Basically it's consult-org-heading across all agenda files. A little slow for giant files but pretty good. I updated the function to correctly handle adding an :ID: and linking to other files.

No I didn't, mostly because I use a single Org file per context. But good to know nevertheless.
