allow calculator to keep recent calculation history on close
It would be really helpful to allow gnome-calculator to keep the history of calculations across app open/close.
Maybe keep this off by default is performance/storage is a concern and allow this behavior to be enabled via preferences.
current behavior:
- open gnome-calculator
- do a 2+2 operation
- close the app
- re-open gnome-calculator
- no previous calculations to show
expected feature:
- open gnome-calculator
- do a 2+2 operation
- close the app
- re-open gnome-calculator
- the 2+2 calculation is shown in the previous calculations stack
