If Flow supported the same collection types that are available in Apex, it would be even more useful and performant. For instance, have you ever had to de-duplicate a collection? You probably either created a looping (or similar) mechanism or implemented an invokable Apex action to accomplish this. What if you could create a collection variable that didn't allow duplicates in the first place, so that every list value would always be unique?

I've posted an idea on ideaexchange to expand the collection types available in Flow. This would be a tremendous step in the evolution of "no-code" development tools. Please upvote if you also think this would be a useful addition. Thanks!
