that's a high value incrementand best would be if you could also let the customizer to control if he list appears (by default) expanded or collapsed.(maybe have a collapse/expand all in the navigation would be of added UX value).to you put the cherry on top, add count to itScenarios: I had several times the requirements that in an existing solution where you had anentity 1 (e.g. event) and an intersect entity 2 (e.g. participants) which contained a lookup to an account (B2B) and contact (where you managed the event participation processes including status such as no show or cancellations) -> no way direct N:N relationship with hidden intersect as you need the intersect entity business process wise.and the entity 3: Account (or contact in a B2B scenario the contact participates on behalf of the account...). You wanted certainly have the list of participants, but also the managers just wanted a list of (unique!) Accounts on one glimpse without having to fidget around with grouping ("too many clicks")... or (worse yet) manually collapsing the 100+ participants. As a YY manager, I want to open the AB form and see the list of unique Accounts, unique Contacts (best including total count) in separate thanks to default grouping and default collapsed display.Use cases: e.g. List grooming (Oh, I see my key account has not yet one of their contacts signed up to our flag ship event, ... I will follow-up...!), quick information from how many accounts do we have contacts participating on this event. Instead of events you could use any other such as Opportunity and line item grouping by product type and more.
