quite often I have pages with multiple tabs (even though I try to avoid them as they are near in visible to users with the current UI design).
Later I might update the columns shown in a given tab and want to propagate that update to all tabs (as the tabs usually are just different filters).
There is no easy way to do this afaik, so I end up doing the same change time and time again.
There is no way to copy/paste a layout from one page/tab to another on the fly, is there?!
