Ability to manipulate individual tasks

[accidentalrebel]

Thank you for making this. It has most of what I need except the ability to manipulate (list, delete, move, mark) individual tasks.

I have done some personal modifications to the code that allows to do this. Right now I am successful in listing each individual task details. I'll work on the other commands, I don't think it would be that difficult.

Are you open to a pull request once I finish this? Thanks!
