Listary 5 Beta (5.00.2334)

I understand that I can switch to Everything as a search engine instead of the Listary’s default one from here.
However, I couldn’t find this option in Listary 5 Beta. Have I just missed it or is it not yet supported in 5 beta yet?
Also, when Everything is used, does Listary respect any of the settings from Everything main window (e.g. Match Case) or is it completely different set of configuration just using background service?
Thank you
