Taxfiler has/had a Job Notes tab for each year that was useful for recording details extracted from HMRC API (against later changes/updates by HMRC systems) and notes of discussions relevant to the year with the client and views taken on an aspect within the return. This does not appear to exist (or sadly have carried over in Data Migration) but would be a welcome addition.
Agreed. Notes tab perhaps in the status section of the Personal/Pship & Company tax returns modules
