So you've convinced me that two messages would be a Good Thing, but I'd vote for a Hide and a ReleaseResources message, with the latter being sent if we're going to discard a Layout (possibly because we're going to discard a Workspace) or before we exit (in which case it should always be called before we show the Layout).
Note that in any case NonVisible must be treated as a superset of LayoutSwitch, since once a LayoutSwitch is received, NonVisible messages will *not* be received. i.e. anything that must be done in response to NonVisible must also be done in response to LayoutSwitch.
Well, let me summarize, since I'm quite loosing myself. A layout must respond at least to 3 events: 1. a change in the stack -> UnDoLayout 2. a change in visibility: A. workspace got hidden B. LayoutSwitch -> the layout is not reachable anymore 3. xmonad is going to be restarted. We need 3 messages: Refresh, Hide, ReleaseResourcses (the third one for LayoutSwitch/restart). Or we could do it with 2 messages (Refresh/Hide) and a method for a mod-q restart. Which brings me to another consideration: should we add methods or messages? They seem to me equal in result. Andrea
