The Details+Thumbnail button in DOpus 11.5 looks like it's a toggle button, and it's associated with this code:
which to me looks like it is supposed to be able to toggle the additional thumbnail column on and off (even though I can't say I really understand the syntax of that last line). However, this does not work for me: If I click it in standard details mode, the button is shown in an on-mode, and the thumbnail column appears. I would like to be able to click it again to have the thumbnail column disappear, but clicking the button again does nothing for me. It stays toggled on, and the thumbnail column remains. Am I missing something here?
If I switch to some other view (say, list), and then back to details, the thumbnail column remains. The only way for me to remove it is via directly removing it in the file display.
