Problem Statement
Calculator currently does not have a settings page, which will block future work. The current about dialog is also inconsistent with many other Microsoft apps.

Evidence or User Insights
Many suggested features have suggested adding options in settings (#538, #486, #485, #393, #382, #215), and while we have not accepted all of these pitches, it is inevitable that there will be functionality requiring settings UX.

Proposal
Replace current about dialog with settings page.

Goals

• Replace current about dialog with settings page
• Be consistent with settings UX patterns established in other Microsoft apps
• Add basic theme selection option common across many other apps

Non-Goals

• Add any additional options at this time

Low-Fidelity Concept

Requested Assignment
I'm just suggesting this idea. I don't want to implement it.
