Sorry, i can't find it. Searching in the help file is overwhelming. Was it Set, or Prefs, or Styles?
Prefs Layout came close, but i want to close the previous lister in that case, not having the new one on top. Also, i don't really know the name of the default lister, when i save it, making it difficult to load the right lister.
Edit, i was using a saved user layout for many years, as well as a button to load my preferred tab sets, but have changed now to only save the default lister, which is just two clicks instead of several style and tabgoup saves.
