wxHexEditor is simply the best free and open source hex editor for any platform. Its features can hardly be found in any other similar tool, the most important being the possibility of editing HUGE files with no slowdown. While other hex editors will run out of RAM when opening files weighing in at several gigabytes, wxHexEditor will just work as if you are editing a small file. The only other tool sporting more or less the same features is the freeware HxD which is non-free and only available on Windows. I would REALLY love to see it added in [pcr]. The PKGBUILD should be modified according to the following to build it with GTK3 instead of GTK2:
