Dark Mode option

I really wish the app had a Dark Mode option. These days, most modern apps let you switch between light and dark themes, and it makes a huge difference for comfort.

For example, I often use the app at night, and the bright white background can be hard on my eyes. Dark Mode would not only make it more pleasant to use in low-light settings but also give users the choice to match their personal preference (many people just prefer the darker look).

Could you please add a Dark Mode option so we can switch between light and dark themes as needed?
