On (re)starting the IDE, previously active connections show in the OpenShift Explorer tab. I think this is probably intended behaviour and not a bug. But I do not think this behaviour is useful for users.

On (re)starting the IDE, the connections listed in the OpenShift Explorer tab are inactive. To get active connections, a user has to click the 'Connect to OpenShift' icon and still pick a previous or new connection. So I cannot see the benefit to the user of listing previously active connections in the OpenShift Explorer tab.

I think it would be simpler from a user perspective if the OpenShift Explorer tab was always empty when the IDE starts (since no connections are active). Then, as currently happens, when the user clicks the 'Connect to OpenShift' icon they will see the list of previous connections and can choose from these or pick a new one.
