- Free - I don't use hex editors enough to justify a $40 editor.
- Unicode capabilities
- byte-level editing
- Cursor tracking between hex and text frames
- hex and ASCII/Unicode text searches
- File comparison - what has changed?
The only thing I would like to see is a file comparison feature. It helps in hacking another program: save a copy of some program's data, then make a change through the program and compare with the reference file. There may be a way to do this through the scripting interface (another neat feature), but it would be nice to see that in the application.
