We have a request in the german forum, how this would be possible:
the last used lister to regain active status (when changing to the Opus task, i suppose) or the last used lister to be opened. In other words, he´d like to know the code for this, to make a customized version of what is easily possible by configuring the desktop/task bar double clicks. He tried "go new", but was unhappy with the results, since new listers kept popping up & he only wants a single one.
