Power Apps To-Do List

I need a lightweight yet polished to-do manager built entirely in Microsoft Power Apps so it works seamlessly across desktop, mobile, and Microsoft Teams. All users will sign in with their existing Microsoft Account, so please wire the security model to Azure AD groups rather than rolling your own login.

Core features I must see in the first release:
• Task creation and editing with an intuitive form
• Due-date-driven notifications (push and/or email)
• Simple priority levels that can be filtered and color-coded

I’m happy for you to store data in a SharePoint list or Dataverse—choose whichever lets us scale and report easily, but explain the trade-offs. The app should follow Microsoft’s Fluent UI styling where possible, and I want clean, commented formulae so my team can tweak them later. A brief hand-off video or live walk-through is part of the deliverable. Once I import the package into our tenant and see tasks syncing, reminders firing, and priority filters working, the job is done.
