Rise 360 PDF

I wondered is there any work going to be done on the PDF that is downloadable from Rise? For accessibility purposes, i.e. screen readers the alternative text of image description inserted in Rise doesn't go into the images description in the PDF, so it reads 'image with no description' even if there is one in there on Rise. The PDF a massive file (number of pages) with lots of white empty space during the PDF. Also, it would be good to be able to remove buttons and audio icons as these clutter the PDF with no meaning to the reader of the PDF. Thanks
