Allow to reorder xobjects

It would be useful to be able to reorder the xobjects in the object editor.
My usecase is the following: I'm creating a class sheet with lots of Javascript and I'm trying to create xobjects for each set of concepts I manipulate, like I would do with different files. The problem is that I also need to create modules that depends on each other, and so I might create afterwards a new module and refactor and existing module to create a dependency on it: in such case I'd like to reorder my module so that my dependent module is placed after the new module.
