changing the extensions as you suggested did not work for me.
for some reason the settings were not saved, too late 4 me to investigate the issue.
but hey, i found another work-around and a (potential) bug.
actually you don't need to change the extensions,
you may right click on the title in the quick view section to change to "text" or press the dang shortcut.
unfortunately the highlight toolbar is hidden after the change. I did not find a way to get it back only via
a work-around by quick filtering the file name, the tool bar simsalabim re-appeared.
