Hello.
I tend to leave my Status as  Away and people still know when I'm on the computer or not, obviously because of one Plus features(show contacts as "Idle" when appropriate).
I know I could leave it on Appear Offline, but it is useful that I leave on, in case people want to leave me a message anyway.
My suggestion is a feature like "Do not send User Is Typing notifications", which is very useful by the way.
Any other suggestions or solutions to this ?
Thank you

There is a script with this funtion...
(After opening it, send /typinginvisible in a conversation to enable it)

Plus! already has the feature: enabled in Options > Conversations > Main.
