Throttle textbox change

Could you please throttle update of indicators?

I have an indicator heavy on calculations and when I want to change a parameter say to 0.1234 it becomes unresponsive because it forces the update of indicator on every new key press. To get to the value 0.1234 the indicator is updated on each value entered like 0, 0.1, 0.12, 0.123, 0.1234 totally 5 times instead of 1 time.

If the update is throttled with each key press like 100-200ms it will update the indicator 1 time only and save us time and nerves. :)
