Task into a folder from the task creation window
In order to save time it is necessary to be able to put a newly created task into a specific task folder on creation.
So when you're creating a new task you should be able to browse through available folders or create a new folder right from the task creation window. (should work similar to the category setting for a task)
Currently you have to create a task (e.g. by flagging an email message) and then you need to go to tasks and distribute newly created task into a specific folder which is not convenient and consumes additional time.
