Dynamically resize window on split/'Other file display'

I don't know the names of all the bits and pieces I'm trying to describe, so apologies in advance if this seems incomprehensible.

Using the |> button on the right side of the explorer path window splits the current window in two (small halves). Is there a way to automatically expand the entire DOpus window when you split the viewer?


I click the |> button

| folder tree |____tab____| '|>' button | X

current results:

| folder tree |_tab_|_tab_| '|>' button | X

desired results:

| folder tree |_____tab_____|_____tab_____| '|>' button | X

You could have a script that responds to OnListerUIChange and then uses Set LISTERSIZE to adjust the size of the window if the dual display turns on or off.
