Hex mode should have features like a good debugger Memory view window.
Namely, options to control the number of bytes per line, and how the data is decoded.
Grouping of the hex data: Bytes, shorts, long, etc.
Number of groups per line.
Of course, once you have more than a byte at a time: Little endian / bit endian.
The right-side now is just the ASCII version of the data .... and there should be a range of possibilities here.
ASCII/UTF-8, UTF-16, integers, floating point, disassembly.
