I am aware of Close ALLLISTERS=collapse,unique to collapse multiple listers into one. Is there a simple way of doing the same thing to collapse a Dual into a Single? I know I could script this but something like Close DUAL=collapse,unique would be nice.
I think only a script could do it a the moment, which is somewhat ugly/fiddly as only the active tab can be moved, so you have to activate each tab, then move it, which causes some flickering while it happens.
