Trello.com is nicely done, efficient and very clear task management tool. You can use it for managing your weekly plans/tasks and you can create multiple boards and then moving task from the left to the right.
For example, you can have three simple boards:
- What need to be done
- What is done and in testing phase
- What is finished, tested and published
It is even efficient to follow Scrum methodology in a simple way – nice for small teams and their collaboration. We really like it and use it on a daily basis.
There is also similar tool from Google named Google Keep which I don’t like at all. UX from Google guys is for me always complicated, over featured and not user friendly.
