Possibility for users to turn chat off?

Hi,

first I really want to thank you for such a already well developed chat module. When I started some research a few months ago to find a chat in Drupal I did not find a really good project but this one seems to be very promising!

I just played a little bit with this module and feel that this could realy meet my needs for a project of mine. At least one thing could be wished by users: to turn the chat off - for a while or fully. If someone would not like to use this chat in general I think with some PHP playing in the visibilty settings it could be solved easily. But what if someone would like to turn the chat off for a few minutes and to turn it on again a little bit later?

I tried "Go idle" but this just seems to give the user image in the "Online users" list a yellow ball - if a another user clicks on this idling user the idling user still receives messages and the tabs are blinking if a new message comes in. When I click on "mute" I think this just turns off the sound when a new message arrives.

Best,
Tobias
