[telmich]

I was looking for an option in element-web to opt-in users automatically into threading, without going to the labs menu - is this already an option? (Did not find it, that's why I am asking here)

[t3chguy]

@telmich you can tweak default values via config.json e.g https://develop.element.io/config.json does with feature_spotlight - See https://github.com/vector-im/element-web/blob/develop/docs/labs.md for full list
