[Feature request] Option to view pending tasks and done tasks at the same time #98

Is your feature request related to a problem? Please describe.

Describe the solution you'd like
It would be nice if users could have the option to show at the same time tasks that have already been done and pending tasks.

Lest say I have to do several tasks today. It would help to have a better feeling of fullfillment (or progression) if I could see how I am proceeding through them.

This is something that I usually do on paper. I make a list of what I have to do and then I scratch the task that I have just finished.
