When clicking on my profile Icon on the main GoG page, I notice there is a Friends listing and a Chat option. Have these been there for a while and I'm just now noticing? Also, when viewing my profile via the website, I noticed it shows me as Online, I could have sworn previously when signed in via the website my status always previously showed as offline, until yesterday.

Private/direct message function has been here for ten years at least. Friends much shorter, about four and a half years.
