Online status of clients
I think this was discussed somewhere around here, can't find it.
I know there's an Action to check the status, but having a live feedback like a color dot or something would be helpful. At least in a Computer page of individual computers, but having it in the Computer lists would be very helpful, too.
And as you once mentioned the growing number of information in columns of computer lists, there could be more options for customizing the views, choosing columns which we need etc.
