I'm not sure if I understand. Isn't this a normal thing, Amazon just made it look like you're normal one, plus "Amazon"? I could be misunderstanding.

edit judging by the down votes I guess I misunderstood?

You've been able to capture and replace context menus in browsers for years. I don't use them in my development because they're annoying but this is one that I played with one time:

https://carbon-components-svelte.onrender.com/components/ContextMenu

(The feature has been Dollar Store DRM for years - that's how you just disable the context menu altogether. "We have DRM at home"- type DRM.)

To be clear, the reason this isn't common is because of OP's response -- it feels intrusive and the more "value" it adds (ie how customized it is) is proportional to how intrusive it feels.

To make matters worse, as far as I know, you can't replace the context menu just sometimes, like, it would be cool to just customize options on images for example, or links -- but it's whole page or nothing -- so using the feature at all means using it everywhere, and, for me anyway, it's kind of a lot of effort, which sits on the scale with "intrusive and annoying" to outweigh the value add.
