Yeah. xD HTML is allowed within the text tool. lol
Now to work on some other things, like dragging and dropping the text wherever you want.
Drag and drop isn't supported with dsi or 3ds so a different way of doing it would be like a JavaScript thing that detects where they picked it up at and where they are moving the mouse and when they let go the item would go there but that may not work very well
If you need it to update every second on where they're moving the item to then try making some type of function that will update every 1 second that using some type of jquery or DOM
