We ever wrote in the older post that in order to make your invisible to only some of chosen friends on Facebook Chat, you need to create a group of chat and the turn in on / off manually. This trick doesn’t work anymore because FB chat have rolled out new user interface and design. But this time another upgrade from Facebook Chat teams make this “visibility option” can be done again. It called as Advanced Chat Settings Friends Availability / Visibility ( See the image below).
By having this feature, you will be able to determine which ones of your folks that you gonna let to see you are online and which ones that you not gonna let to see it. It also provides the ability to make all your friend see you being online but added the exception for others. The fastest way to add to this list would be by adding the listed / groups that you already had (in Google Plus it called “circle”). It would avoid manually adding friends one by one that will take too much time to do that.
