Add custom commands to the right-click context menu

[WWL]

Can a custom command be added to the right-click context menu?
e.g. Add the command 'Close All Tabs to the Right' when right-clicking on a tab.

What kind of custom command?
And which right-click context menu?

[WWL]

Add the command 'Close All Tabs to the Right' when right-clicking on a Tab, like on Google Chrome.

A command 'Close All Tabs to the Right' does not exist. So that's a wish for that command?

[WWL]

I have a custom script that will execute this command 'Close All Tabs to the Right'. Is it possible to add this command to the context menu when right-clicking on a Tab?

Ah, I see. No, not possible ATM.
