  - Full sympy expression editor with virtual keyboard.
  - Ability to "UNDO" multiple times.

"Long term" updates:

  - Function pretty view on stack element long press.
  - Documented functions.
  - tap on stack to include in expression when keyboard open ?
  - tap on expression to evaluate ?
  - Auto simplify option ? use kernS if no simplify
  - quick precision with blue button + orange button + number ?

  - vibration ?
  - switcher de pile
  - save stack
