[Users] Shortcut key to fancy render view for HTML messages

[Ralf Mardorf]

Hi,

Linux Mint is based upon official ubuntu repositories. Claws mail as
well as the claws-mail-fancy-plugin and libwebkitgtk-1.0-0 are
from the official Ubuntu universe repository. The universe repository is
maintained by the community and insecure.

"Universe – Community-Maintained, Open-Source Software:

Licence: Open source
Updates: Canonical does not provide update.
Some updates may be provided by the Ubuntu community." -

Regarding webkit read
https://blogs.gnome.org/mcatanzaro/2016/02/01/on-webkit-security-updates/ .

To cut a long story short, official Arch Linux repositories don't
provide webkitgtk anymore and claws-mail from official Arch
repositories is build without the fancy plugin.

Better add an action to display HTML mails with a webbrowser. To some
extent automatically selecting HTML and displaying it as text does
work, too.

Regards,
Ralf
