One of the things I like to do in my channel is say hello to new viewers I've never seen before that hang out for more than a few minutes...it's a great way to capture new people's attention and keep them as long time viewers.
A feature I would love to see is having a configurable way to have chatter accounts that have been in the channel that are there for the first time and have been there for a minimum specified amount of time...ideally I'd like the ability to either place them at the top of my channel list or display in priority sequence before the normal chatters are shown but after the vips are displayed.
Obviously a feature like this would need to be able to be toggled on/off at the very least as larger channels may not be able to manage this well but it'd be a godsend for the smaller channels to try to captivate their audience and would be a very unique feature.
