Ability to "mark" a contact to be always visible
Some my friends used to the "invisible" mode. It seems they are not online. But I know they are. I have lots of contacts and it is impossible to show them all.
It would be nice to "mark" a user to be always visible, even if you check "show offline contacts". Is it technologicaly possible (I mean - does Jabber support this or do we need to store this kind of information on the user side)?
