Styling

Request to change icon color and position for copy and share button, even I often using copy rather than share. I kindly hard to find the button.

• Request to change background color to #000 in .theme-dark .icon and .icon
• Request to change the position of the icon button share and copy to the bottom, so I just copy the "long" output without scroll to the break point that will be difficult to find if the history are not cleared before the last command.

You would love the result of this change if you use a lot of this tools like used to be.
Btw, thanks for your tools. Already help me a lot for simple cases.
