Autojoin and rejoin on disconnect are nice features, but they are not perfect:
(1) When I have to join a channel with a password, the password is not applied when I rejoin on disconnect. It would be nice if the channel password was applied with every auto-join.
(2) I would like to have a button "Auto-join now" in the favorites dialog, so I can decide to auto-join or not when "Popup favorites on connect" is enabled and "Enable join on connect" is disabled.

Hmz, somebody told me to use "perform on connect" to rejoin channels with a key. That works fine ... but still it looks strange to me that the standard autojoin on connect doesn't take passwords into account. Well, anyhow, I'm satisfied with the perform ...
