Finally! The most wanted and waited for feature for the tasklist. Now if you want to reorder the tasklist just grab any task by the popup icon at the left, drag it anywhere you need, and drop it there. If you drag the parent task then all it's children will be moved as well. If you drag one of the selected tasks then all selected tasks and all their children will be moved.
There are still some things left to improve (you cannot change task indentation level by drag'n'drop and still need to open popup menu to do that) but this is a great step forward in usability. Any kind of feedback is appreciated.
