Open in dual vertical or horizontal

How does one get the Opus 9.5 to open in a dual pane as default, I personally would like the proggie to open in dual horizontal
Step by step instructions if possible

You can type ">" (this will open some command line) & paste in following:


After that you can save this under -> settings -> lister layouts. Then you can look under -> settings -> preferences -> opus start & set this saved layout as the standard for your preferred Opus launch.

Easier way:

[ul][li]Change to the horizontal layout the way you usually do (presumably pushing the = or || button next to the X close button)
[li]Use Settings -> Set as Default Lister to save your current setup as the default.[/li][/ul]

No need to type any commands or change to a startup layout.

Thanks, saving as default Lister did the trick
