This piece of software is excellent. I love that I can view as 8bit, 16bit, 32bit, or 64bit and in either endianness. I use this program to view in little endian, then paste into a new file to convert between endians. I think this would be a good next feature to have so I wouldn't have to do the work around. This program is off to a great start. I love it!

Mostly useless - I downloaded this to do a hex search of a file, and this thing doesn't do anything when you give it a value to search.

Stop releasing software that's half-done!

In response to "Mostly useless - I downloaded this to do a hex search of a file... Stop releasing software that's half-done!"

Even if this program's search is broken, that doesn't make it mostly useless to everyone, and may be completely useful to those not needing to search.

Note the version number: 0.6.1. By convention

Why Panther-only?

For any of a hundred different reasons why Panther is better than Jaguar. Really, with Tiger out soon, 10.2 compatibility is and should be an afterthought.

Until Apple supports Panther on all Macs they support Jaguar on, Jaguar support should not be an afterthought. If the Mozilla team can keep Firefox, the most advanced browser in the world, compatible back to Mac OS 10.1.5, surely an app that doesn't push the boundaries of the possible nearly as hard can handle Jaguar?

There are specific features that require Panther, and if an application requires advanced Webkit or Perl or whatever then, sure, it can leave Jaguar behind. Otherwise, writing portable software is only common courtesy.

Promising, so promising! I look forward to a cocoa hex-editor, but this one isn't there yet. Huge CPU usage spikes (to 100% for me) when trying to select bytes are the biggest problem I see.

I will see, what I can do about that CPU-usage problem. Should be a trivial fix, hopefully.

About "editor"... it is in plans, but not nearest ones. Also, "editor" will most probably be shareware (though, a cheap one), while "viewer" will be free
