Online users do not always indicate "available".

The user status really should have all the capabilities that are in Skype for Business.
Like the ability to show a user as inactive when the computer is idle for this many minutes ___
And change my status from Inactive to away after this many minutes ____
Also, what about the option to show "Do not Disturb" when desktop sharing?
Please correct me if these options already exist.
