Making form item ordering more user-friendly

I was just writing up some help docs on creating a survey and realized that surveys could be much simpler with some Ajax integratrion, (easier said than done, and unfortunately I lack the skills to do it). This is particualary true with ordering form items. The weights are already limiting because there is only -5 through 5 which creates a nightmare scenario if you have 15 form items and need to insert a new one somewhere in the middle later. A drag and drop ordering could be a huge improvement here (maybe adding more weights would help for now).

Down the road, it may be possible to handle the whole survey creationg in Ajax so a user can see exactly where their new question is going. Maybe an "insert new item here" link could be added for now between each form item when viewing the "form" tab?

If none of these options seem likely, how about not using weights for form items and using a simple order, 1,2,3,4,5, etc.? I should note that I'm referring to the 4.6 version as I haven't tried 4.7 version yet.

In the meantime I'll try to get my docs up in the handbook for review.
