Please implement the following feature as described by DjVuLibre:
"When page titles are available, recent versions of the DjVuLibre viewers display these page titles instead of page numbers and also accept them in page selection options."
As an example, the first 10 pages could be titled i,ii,iii...ix,x and then page 11,12,13 could be titled 1,2,3 etc so that jumping to page number (title) 20 really jumps to the 30th page. The same would hold for in-document links. Just open the attached DjVu file in DjView4 to see how this should work.
