Display Selected Contract Size in Smart DOM

When using hotkeys to quickly adjust contract size, the currently selected size is not visible in the Smart DOM. At the moment, the only way to verify the selected contract size is by opening the trading panel.

Since I execute trades directly from the DOM, I keep the trading panel closed to save screen space. It would be very helpful to add a small indicator or box at the bottom of the Smart DOM displaying the currently selected contract size.

This would improve usability and reduce the risk of placing orders with the wrong size when trading exclusively from the DOM.
