How to unhide contact? I've hidden contact in hangouts' dialog for opening new hangout, by clicking on one of icons of most frequent contacts, then in "Contact options"->"Hide contact":



Now I wonder how to "unhide" it?

(Notes: Currently using "Hangouts Version 2.1.100 (1151589-30)")
Problem solved with Hangouts version 2.1.223. 
In "settings" we now have an option do "unhide" contacts.
Thanks Google.
