What I'm requesting is for your engine-level ad-blocker to override the core functionality and provide (enabled) information about blocked content like a traditional extension would.

basically, instead of seeing this:
(I'm aware that this is core functionality, not your ad-blocker)

when this "extension" is enabled:

the displayed blocked information would optionally be overridden to look like something more expected:

this is useful for:

• development: providing quick and easy information of what content should be removed.
• Knowledge: paranoid users (like me) who want to know everything about what content is being blocked for various uses
• security: experts who need to know this information to keep their databases up to date
• control: if users want the option to allow specific domains regardless of the warning

note that this request asks merging the ad blocker with the content blocker if this for some reason isn't done already
