Syntax Error? (with possible fix)

This might just be a typo. Line 1559:

         $this->orderby[] = str_replace('ORDER BY ', '', $result);

generated a "[] operator not supported for strings" error, when I tried to order by Note Title. It seems to work fine when I changed it to:

         $this->orderby = str_replace('ORDER BY ', '', $result);

Doesn't seem worth rolling a patch for.
I guess there are not a lot of folk testing views for 4.6 yet. Their loss - just wait until they hear it is the best thing since sliced bread.
