Kcalc: show last operation entered
Kcalc does not show the list of operations (=, +, -, etc.) that have just been entered. It only show the results. Sometimes I lose track of which operation I have just entered and I must start all the calculations from the beginning.
For example, if the result window shows '5', I don't know whether I typed '2+3=' (with '=' being the 'Enter' key), or I typed '2+3+' (with 5 being an intermediary result.
Now, if I type '+2', I'll get different results depending on the state:
'2+3=+2' => I get 7.
'2+3++2' => I get 12.
Those results are logical from the point of view of the inner arithmetic. However, from the user's point of view, when the user got distracted, it's unclear which operation is going to be performed next.
Kcalc should keep and display a history of which operations have just been performed, allowing the user to track back key strokes.
