Problem Statement
When attempting to use Calculator with other application, such as a spreadsheet, Calculator will lose focus when you click on the other app (e.g. to scroll/copy). Users have requested the ability to pin Calculator on top of other windows to facilitate ongoing use with other apps.

Evidence or User Insights
This is our second-highest customer feedback request in Feedback Hub with some users reporting their only alternative is to pay for an app which is sticky.

Proposal
Add the ability for users to pin Calculator on top of other windows.

Goals

• Users can easily pin/unpin the Calculator window on top
• Users can easily continue with other tasks while Calculator is pinned
• Users have access to full Calculator functionality, but can always perform at least basic calculations when in the more compact view (smaller than currently allowed minimum window sizing)

Non-Goals

• Parity with the full version of the app​​ when in smallest of layout states

Low-Fidelity Concept
