This is more of a nitpick than a suggestion, but I thought I'd bring it up.

When using the "Contact Information" right-click menu item, I think it would be useful if the contact's status would be displayed. You can see the last status change in the "Last events" section, but it's not always readily accessible. I attached an example.

For those of you wondering "Why not just look at the contact list?", my point is to use this feature to look at the status of blocked contacts.

I see what you mean about that popup, but I don't think such a feature would be useful to most people. Still, it should be a simple addition.

Already possible (I remember I read about this addition in changelog of Plus! 4.50 but I couldn't find it now, I think it was in the changelog in Beta site and Patchou forgot adding that information in the changelog at official site)

For example in this picture, your contact's status is offline. See the msn buddy lhs of "Last online" line. But you know there are more statuses with the same buddy images so to get the exact status of contact, show that contact in your desktop (right click>Messenger Plus! Features>Show on Desktop) and hover your mouse on it. The tooltip will say the exact status of that contact.

I hope this will be enough for you.
