subtask suggestion

I would like the button "add subtask" to remain under all high impact tasks even after first creating it (it disappears after a while and I have to make more clicks to add subtasks that I may think of along the way as the task change)

order "done" subtasks so that they are at the bottom of the subtask list for easier overview of what subtasks are still undone

Thank you! 

(I think weekplan is a great tool, the best I've found for planning my different roles and focus areas so far)
