Hi, I haven't used the beta filters much bc I think they have some work to do before I roll it out to my org.
I've only used it so far for seeing team + status. For example, in a project with multiple teams involved a certain has only wanted to see their team's tasks (filter 1) and if it's ready to start (filter 2). Those two filters have merit standing on their own for different purposes so they're two filters, but I've used them to stack for this scenario.
If this helped you, please mark correct to help others : )
