Not every Lykewise set is a stranger vetting exercise. Sometimes you are using it with a partner, a close friend, or someone you already trust. The original design leaned toward caution -- test questions, safety thresholds, one person creating the set and the other responding. That makes sense for new connections, but it felt heavy-handed for people who are already close.
Mutual mode changes the dynamic. When you create a set with mutual mode on, both people are equals. There are no test questions, no safety thresholds, and the results look identical from both sides. It is the right choice when you are exploring with someone you trust and you just want to know where your interests overlap without any of the safety scaffolding getting in the way.
Role tags are new on questions where direction matters. If a question is about rope, for example, you can now say whether you are interested as a rigger or as a rope bunny -- or either. Same for D/s questions, impact play, and anything else where top and bottom are different experiences. This means matches are smarter. Two people who both want to be tied up will not match on a rope question anymore, because the roles are complementary -- a match only counts when the roles fit together, or when someone picks "either."
Saved answers solve the problem of answering the same questions over and over. If you use Lykewise with multiple people, your answers to questions like "would enjoy sensation play" probably do not change from person to person. You can now save your current answers as personal defaults and load them into future sets. They only fill in questions you have not already answered, so you can still override for specific people.
Related to that -- if you are creating a set with multiple people, there is now a toggle to use the same answers for everyone. Answer once and it applies across the board. You can always switch to per-person answers if someone is different.
