One of the things that could be really useful would be the ability to set up multiple document sets with the ability to start a QA session based around one or the sets.
If the sets can be shared this would enable people to set up guidance tools which could rapidly increase the utility of R1 by turning on any QA tools which are of use and shared.
This could potentially be extended to the likes of Supabase or Airtable or another cloud provider (ideally with a suitable tutorial showing how to use their free tiers for this) to provide straightfoward ways for users to set up their own datasets for this, but even with a minimal amount of simple storage available various useful things could be implemented.
