nope, just testing. the issue I see here is that toggling the view mode should not close the viewer window.
opening a text file, then turning off hex view does not work either bilder uploaden
although hex view is turned of, clicking the button toggles hex view.
The hex view option should probably be hidden or disabled in that situation, and that's on our list to look at implementing.
It's not a high priority as it only happens when you tell Opus to use something you've told it to disable. The default Opus 12 setup does not have the hex view option at the toolbar's top level, either, so it's unlikely to be clicked by mistake.
Please link your account if you'd like it to be a higher priority.
