I always assumed this was possible until I tried to do it this morning. I tried to click and drag a task out from under it's parent task and make it a task. TD wouldn't allow it. It would only allow me to make it a subtask of another task. Not a huge thing, but definitely a PITA. Is this on "the list"?
You can turn a subtask into a task by dragging it out of it's parent and dropping it somewhere that is not on top of another task. For example, drag it to the left and drop it on the left sidebar. I just tested this and I was able to do it in Chrome and Firefox. If you can't this to work, please let us know what browser you are using.
Thanks! I didn't try dragging to the left, which worked. I only tried up and down. It definitely doesn't work dragging it up or down as it never shows the thin red line between tasks (unless the adjacent task is a subtask), only the grayed task that it will become a subtask of. I'm using FF 14.01 in Win2000. But dragging to the left is good enough.
