ZX Notepad. Which one??

Thanks Spensor, shame that all functions are not present just in one program. But anyway, many thanks for tips.

If you wanna use 'all-in-one' packages, take a look to commanders- PerfectCommander, RealCommander, QuickCommander etc. If I'm not mistaken, some of them have build-in editor. And almost all of them have hexdump editors (disk doctors etc). Plugin system can help you to do anything.

BTW, ACEdit also supports plugins, so you can write your own.
