Would it be possible to add ITRK (track number) and IFRM (total number of tracks) to RIFF INFO metadata? Windows Explorer uses ITRK to display the track number. I think it also probably displays IFRM as total number of tracks (like 6/10) but I haven’t found a program that writes IFRM yet, and Windows Explorer doesn’t allow me to edit the values. But it’s apparently used elsewhere.

Also IPRD (Product in Wavelab) is Album Title in Windows Explorer (and probably Mac Finder), and also on the tag mapping page.
