Option broken? Left click on active thumbnail minimizes the window

What is the issue here? This option modifies the left click action, not the right click action.

DOH! The other right then... I feel ashamed. Works as described, I expected something else, but not getting the point of this feature :D

BTW: Does "Fixed the disable_items_drag advanced option, which caused the thumbnail previews to not appear." mean that previews will always show when you hover an application in the taskbar? I did not work reliably in some older version, but never figured out when or when not.

It means that the hover settings aren't affected by the disable_items_drag advanced option. If previews appear without it, they should also appear with the option.
