Use Dragonfly Offline (updated)

A revised example for Opera version 11 is on its way.
It's impossible for me to think of Opera's Developer tools without bringing to mind Basil's "Little bet on the gee-gees" and his sending Manuel off to place a bet away from the watchful eye of Sybil. "The name of the horse is Dragonfly, but remember Manuel, Sybil No Know."
Back to Opera's Dragonfly
I wanted to run the app locally rather than from Opera's server, as is usual. I didn't bother looking for any documentation on this because Opera's track record at documenting their browser to any useful degree is considerably inept.
Here then, briefly, is how I achieved it, in case anyone else should wish to follow suit.
Download the application from here: https://dragonfly.opera.com/app/core-2-2/zips/
UPDATE: According to the Dragonfly site, the proper Code Repository url is this: http://dragonfly.opera.com/app/zips/ Although at present both files sets match one another.
Unzip it somewhere - mine is at C:\Opera\profile\Opera-Dragonfly - and overwrite the default address (URL), https://dragonfly.opera.com/app/ with the location of your local folder. You can achieve this either by editing your operaprefs.ini file directly, or via Opera's own Preferences Editor.
The operaprefs.ini method:
Developer Tools URL=
(I've not checked, but one should also be able to use the relative address .\profile\Opera-Dragonfly/client-en.xml for running from USB/Network drives)
The Preferences editor method:
You might also wish to add a button or two to access it directly:
Reload from cache (text button)
Dragonfly (text button)
Thanks to Ben at 200ok weblog for providing the source of these buttons.
