How do I save my GUI layout?

Currently using Composer 2018. Every time I open Composer, my GUI layout reverts back to at state where I always have to resize the left and right panes. This is not a huge deal but it is irritating. Is there a setting that will save how my GUI looks regardless of what file I open? It seems like this should be a simple thing but I cannot locate anything obvious that controls this?

Thanks.
