This should be an easy add for @KGN and the team. The code to clear the terminal is already there. They’d just need a button to send the command. I’d submit a pull request, but I’ve had a hell of a time with webpack dependencies and the like when I’ve tried to build gSender.
EDIT: Here’s the relevant code.
Maybe something like this added to the render():
<Button
onClick={() => this.clear()}
style={{
margin: '0px',
height: '100%',
border: 'none',
borderRadius: '0px',
borderLeft: '1px solid #9ca3af',
}}
>
<i className="fa fa-trash" />
</Button>
