Feature: "Undo" button to be unavailable at application start
Would have opened as feature request, but only type "Issue" is available now.
After Calculator (42.0) starts, the Undo button is visible and clickable.
It would be nice if this button were either
- visible, but unclickable, and Tabbing through UI elements wouldn't have it selectable
- not visible at all until any input is made for a calculation
