[notepad++] A hex viewer / editor plugin for Notepad++?

I have had a look through the plugins as well as searched the forum for Notepad++ and have not seen a solution to editing data as hex in Notepad++.

I am after the same kind of functionality that UltraEdit offers (see the screenshot below) where you can edit the document either directly or via entering new hex characters.

Is a completely different (but still free) application an option? I use HxD, and it serves me better than the Notepad++ plugin. It can calculate hashes, open memory of a process, it is fast at opening files of any size, and it works exceptionally well with the clipboard.

I used to use the Notepad++ plugin, but not anymore.

The hex editor plugin mentioned by ellak still works, but it seems that you need the TextFX Characters plugin as well.

I initially installed only the hex plugin and Notepad++ would no longer pop up; instead it started eating memory (killed it at 1.2 GB). I removed it again and for other reasons installed the TextFX plugin (based on Find multiple lines in Notepad++)

Out of curiosity I installed the hex plugin again and now it works.

Note that this is on a fresh install of Windows 7 64 bit.

According to some comments on Super User it still works :) It just should be copied back to the plugins folder (if it's in the disabled folder) or downloaded from Plugins Central. I have downloaded it a few minutes ago and succeeded in using it.

Of course, be warned: this plugin COULD be unstable in some situations - that's why it was disabled.

There is an old plugin called HEX Editor here.

According to this question on Super User it does not work on newer versions of Notepad++ and might have some stability issues, but it still could be useful depending on your needs.
