Someone else suggested this back in 2017, but no traction. Note how many menu items I never use on the layer right click:

I've NEVER used those options. Can we vote for the ability to customize it the same as the application menus? I'm getting old and my eyes are getting worse, so I have trouble seeing the options.
It would be great too if the customize interface would show a preview of the current menu you are modifiying. I like to put colours on my most frequently used items.
