Adium is a GREAT icq client with bunch of cool options and customization, really! But it is missing one very important (at least for me and my friends) option: privacy/invisibility settings. I noticed that in the latest version "invisible" status has been added, but there is still no way to manage my invisible list - add persons who see me in invisible mode and so on. for this i must use the client by icq.com or the flash icq version at go.icq.com. It would be really great to have that feature, wich is supported by all of the x86 icq clients out there.
How exactly do i see this working:
A panel in the Preferences menu, called Privacy / Visibility. There one has a list of all his contacts and can choose wich one can see him while he is invisible and wich one not, or if they can see him at all (even when one is online). Here is a link to a picture of a windows im client called miranda im, and how this has been solved:
