Button in the Message window in Thunderbird?

[mistergom]

Hello!

To save some "clicks", could it be possible to have a button in the Message window of Thunderbird?
So while I'm writing or answering a message, I could select my text and simply click on the AI-Anywhere button to get access to its feature? To avoid to select>right click>select AI-Anywhere menu>click...

Keep up the great work!
