Hi,
Thanks for trying 2.0 Beta 1.
The shell extension is a separate file (DLL file) to allow to be registered on the system. I could include it with the default installation, but it's openly available as a separate add-on, I don't think it's a big deal since it's easily available to download.
About the 64 bit issue, which you kindly offered an registry alternative (thanks!), it's not that simple since the code I got to create the shell extension only works in Win32 systems and did not found an alternative also compatible with Win64 ( I know this issue as been happening in some Delphi apps which bundle Shell Extensions). I never worried much because it was something user's never wished for. I will look into this.
(In fact Twistpad created a similar registry key before it had a separate add-on, but it was dropped because it created some issues in explorer)
Hex edit has always been a possibility, but personally I always thought it a bit out of the bounds of a text editor. I agree it could be something useful, but I must admit it's not something high on the wish list.
Thanks,
