Patchou,
can you add minimize to tray opision? so we can do so like in ICQ

Minimize what to tray? I haven't used ICQ in about 6 or 7 years and further detail would have been nice

The contact list more or less already does.
Conversation windows (IMO) have no place in the tray (too many icons) and even tabbed convos don't belong there, it's just not right. Not to mention it will only add to the somewhat endless number of people which fail to read preference options properly and come complaining on the forums and irc channels wondering where their conversations have disappeared to.

there is a program called

Virtual Dimension

it will do that for u its a pretty nice program i use it here an there for programs that dont hang by the clock an i want em to an stuff so meh u can look into that
