Why on earth would anyone number the bytes right to left? Do you want strings to appear backward as well? But only the portion of a string on one line, the fragments will still be in correct order. Or do you advocate numbering from bottom to top too?
I am talking about the view of the hex data. That view is about showing numbers, and the common complaint about LE is that numbers are reversed, but this is only the case when you break the convention of displaying numbers right to left.
For showing strings it's better to use left to right, as that's the convention for text.
