Compact Mode?

Is it possible to create a Compact Mode like in Adobe Bridge, cause i drag often Images from Opus to Photoshop or Maya, so i would like to switch to a custom made Compact Mode. If not, is it possible to store the Size of the opus window???

You can. Below is a button to change Opus to a window 680 pixels wide by 600 tall.

<?xml version="1.0"?>

Half Size
#newcommand

Set LISTERCMD=Restore
Set LISTERSIZE 680,600

it works fine. i set it in two different layouts. custom1 & compact 1, how is the comand for toogleing between my 2 layouts?

I don't think a toggle button is possible for this but you could make a three-button which you left-click for one size or layout and right-click for the other. And/or a pair of hotkeys, e.g. Ctrl-W and Ctrl-Shift-W or something like that.
