I would, but it would be too much work to actually do properly. It would have to be forgiving to new users. It would have to be able to "Show" all files and formats naively in a window, without having to keep "turning it on".
And the BIG KICKER would be -it would have to handle all of the most popular compression schemes without having to hunt down tons of "supporting" programs to make them work. This is by far the most frustrating thing to a new user with all the IHA,ADF,DMS, ETC. It would have to "just work" with those formats, just by double clicking on them.
