I see in the video that in Directory Opus 12 I can now click on the Status Bar to display the hidden file.
My hidden files display is 3 to the right, and when I click on "Hidden", the word "Everything" moves over to the very left.
How can I make both "Hidden" and "Everything" stay in the same location so I can easily switch back and forth without moving the mouse?
The video is using the (new) default status bar codes. If you're using Opus 12 with a config from older versions then the status bar settings will need updating to make them work the same.
If you just want the defaults, click the Samples drop-down next to the status bar editor and they are in there.
