Main Context menu

I don’t normally post in this category as I’m not into writing stuff but I figured you are the ones that would know.

Is there any way to edit things out of the context menu? I know you can edit extensions for this but I’m wanting to remove the deadwood vanilla things like Hide, Entity info etc that I never use from the context menu.
Actually now that I look at it there are various extensions that I never use from context also and would be happy to remove them.
The menu gets so long and it would be nice to be able to customize it to your workflow.

I would like to add to the request: The ability to reorganize the menus in alphabetical order.
