tasklist - hide finished tasks

I like the task list, which is bundled with confluence. But to improve its usability I lack some features.

I need a switch (button, checkbox, link) that hides finished tasks. I do not want to see them. It would be fine to show only open, only finished and both tasks.

Both finished and open tasks looks same, they can be distinguised only by the state of their checkboxes. So I propose to put CSS styles for finished tasks and make it by default italic/grey.

There are many other features, that would boost productivity of this feature. For example add labels to each task, filters by tasks, deadlines .. But for now I will be happy with hiding finished tasks.
