Feature description

Firstly, thanks for making this application. It is very useful, and the unit conversion is an added bonus!

Currently in the history tab, you can see the calculations you did. But clicking on it, pastes the result in the input menu.

So for example you did 2 + 2, it will paste 4.

Why do you want this feature?

So that we can copy the equation as well and modify it in case of error.

For example, If I accidentally do 2 + 2 instead of 2 * 2, I would have to write whole equation again.

That is only for result right? And I believe that feature is already there. I am talking of equations too.

Yes, it's related, but a different request.
