Relation views should have rules similar to entity views. Specifically the ability to hide or default relation views depending on the entity view.
This would make the combination between entity views and relation views much stronger. If you default an entity view for different team roles, then you can make it so their relation views only pertain to them. Instead we have way too many relation views which makes views look messy and people get lost more easily.
Alternate Proposal: just allow the ability to create empty relation view fields that aren’t tied to one of your relationship fields. It feels like you are already 90% of the way there, because a single relation view field can already have view tabs with different databases that aren’t tied to that relationship field at all.
Right now, my only options are to live with messy entity views that have way too many relation views, or create empty databases as a way to do imitate the alternate proposal above, but this doesn’t seem like good data hygiene.
