And now with tags!

You can now label your tasks using well-known productivity concept known as "tags". Tag is a simple label that you attach to your tasks. You can then use tags to quickly group and search your items.
To start, add tags when creating or editing a task (look, it's just below "description" input field). When you added some tags, new "tag cloud" filtering control will appear in the middle section, over your tasks. You are now able to quickly and easily filter items using tag criteria!
