Feature to collapse, rather than hide, sections of a form

This is an ideal module, thanks for maintaining it.

On some forms, the problem for me is not so much that a given section is there, but that it is expanded. In some cases, such as the edit-account form, which doubles as the registration form out of the box, I really don't want the user to have to look at all the possible settings, but I do want them available to the user if they need them at some point. So hiding them isn't an option, I just want them minimized, so an option to collapse a given field would be ideal if that's not too difficult. I know this is partly solved by rolling sections into a collapsed advanced section for node-creation forms, but there are many other forms, such as the edit-account page, for which there may be the need.

Do others agree?
