Is there a way to disable built-in feature from a plugin?

[ruffp]

I have a customer which is not interested by some feature of the product or by some extension of the feature.

The question is simple: is it possible to deacivate a feature (let say a link) on a page and provide my own feature instead?

For exemple how to override the "Delete selected target groups" link on the "target group" overview page?

Disable user right "show plugin manager".

By meaning disable a feature I was thinking a built-in feature (like the Delete All Recipient link).

I notice I can disable such link in the user rights, but my question is more like this:
If I want to make my own behaviour (like unsubscribre everybody in the mailing) how I can override this through my own plugin?
