useless without dark mode background

Transparent Background of the widget

Transparent Background of the widget, or the adjustment of dark mode and light mode would be nice. I prefer dark mode, so white background doesn't look nice. Thank you ; )

update pomodoro

I would like to add a sound to the Pomodoro timer. sounds such as white noise. Next, I would like to add a sound to let you know when the game is over. I think you need some rest time.
