I wish I could use some of orgrr’s other features, but I think they are mostly predicated on the existence of file links rather than id links.
[[org-node]] looks neat and an improvement over org-roam in many ways.
I haven’t tried it though, as the feature list described ‘separate note piles’ as a won’t fix.
Assuming ‘separate note piles’ means different knowledge bases for different purposes, which I guess it does, then I rely on separate note piles quite heavily.
