Using Opus 11.4, I have two viewer panes open along with the folder tree. On my viewer panes I only want to view Name, Size and Modified columns. I can get to that by right clicking and removing the defaults. However soon as I close and re-open Opus all the other views re-open like Type, Attr etc. So how do I make the new default to only display Name, Size and Modified columns?
I think you mean file displays.
(The viewer pane is where you can view pictures.)
To set the default file display columns, see this FAQ/guide:
