Feature Suggestion: PurgeListeners(event)

[cwolves]

There should be a way to do:

purgeListeners('beforeclose')

or

removeListener('beforeclose'); // no function specified

100% agreement.
Example:
If I load something into a contentPanel that registers events, it is important to unregister listeners when the panel is destroyed (the tab is closed).
(BTW: I am missing the event "beforeremove" in ContentPanel - the "beforeremove" is only fired in the LayoutRegion)
I helped myself with Ext.Ovservable.capture() sometimes, but have to handle ALL events in this case.
