Not much spare time nowadays, but I'll keep it in my mind :) > This raises another question: what would be the best way to save this > kind of stuff IIF possible).

In fact you can use QGIS project files to save plugin-specific data for a plugin - see QgsProject class. In case you'd like to be able to use one set of annotation for different project it would be wiser to save them separately - in a file or a database. Using files for saving annotations (e.g. with python serialization) should be easier to use for user as they won't need to set up a database/table for them etc. And actually user would expect that annotation plugin should work also without postgres database.
