Build me a polished desktop app for Microsoft To Do that feels lightweight and elegant, with a clean interface and strong keyboard control. I want users to be able to sign in, manage their lists and tasks, create, edit, delete, and complete todos, move quickly between lists, search tasks, and mark items like important, my day, planned, reminders, and due dates.

Make it cross platform and include a few nice quality of life touches like dark, black, and sepia themes, an auto night mode, compact mode, scalable text, always on top, sidebar toggle, and update notifications. It should also support custom keyboard shortcuts, including global shortcuts so I can open the app or create tasks from anywhere.

Please keep it feeling modern and snappy, with a simple settings area for preferences. If you need current Microsoft To Do or desktop app docs, look them up online first.
