Codger, if you want to have a look at a relatively simple addon that uses the libdatabroker part of the library you can grab a copy of my AltILevel addon I created 10 years ago. It was still working as of the start of dragonflight. But with some of the minimap having changes this patch ( Tracking frame name changed .. again ) I might have to test it out again rofl.
