            Bug ID: 421519
           Summary: Option to disable HTML security warning and / or allow
                    toggling HTML with shift-H shortcut
           Product: kmail2
           Version: 5.14.0
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Severity: wishlist
          Priority: NOR
         Component: general

SUMMARY

When viewing some HTML messages (not sure what the criterion is) in plain text
mode, a security warning is disabled: 

"Note: This is an HTML message. For security reasons, only the raw HTML code is
shown. If you trust the sender of this message then you can activate formatted
HTML display for this message by clicking here."

The user should be given an option to disable this warning permanently. 

I believe it should be on by default, but after a while it simply takes up
space and is habitually ignored anyway. 

For these specific e-mails, the "toggle HTML" short-cut (default Shift-H) does
not seem to work. The only way to view the original message is to click on the
hyperlink in the security warning message, which is disruptive to users'
keyboard-based workflows. The user should be able to view the original HTML
message without needing to click on the link.



STEPS TO REPRODUCE
1. Receive HTML-only message
2. Open message (or select to view)

OBSERVED RESULT
Message is converted to plain text and the warning is displayed on top of the
message. The "toggle HTML display mode" shortcut does not work. 

EXPECTED RESULT
If the user chooses to ignore the security warning permanently, they should be
able to view the converted message without the security warning and toggle the
HTML display mode using the  "toggle HTML display mode" keyboard shortcut.
