It would be amazing if there was a way to see in which whiteboards is an entity used.
One of our use cases is as follows:
We use whiteboards for flows and entities for various items such as Pages.
We’d like to answer these basic question:
In what flows (whiteboards) are these pages (entities) used?
I second that!
Right now we need to add an additional layer of references to the whiteboard’s parent object, which is manual and thus unreliable.
Nice to see fellow “whiteboards as flows with views” fans! 
Out of curiosity, what other entities go onto your flow?
We usually also add User Groups and Backend API Calls. Also considering Events… Keen to hear your thoughts. 
Out of curiosity, what other entities go onto your flow?
We use Actors (which can refer to user group, user with particular roles and so on) and for the rest we do a variation of Event modelling (wit things such as Commands, Events, Read models)
Interesting, thanks for sharing!
Sounds like a Service Design approach?
also ‘third’ this! 
(and ‘sorry’ I kind of opened a somewhat redundant thread, not seeing this one here, before 
. – I might be justifiable, as this one is very much function + request oriented, while mine wanders a little on and off into some conceptual musings, and some broader questions about the – potential – value of whiteboards as context and work / manipulation interface…)
