Currently to change the weight of a package, you have to scroll all the way to the right if your browser isn't WIDELY opened and click on the "down arrow button" and "edit weight", then a popup window, enter the weight, and then confirm edit. That's two many clicks more than it should be need to edit the weight. If the page can use Ajax/jQuery or whatever so that you just click on the weight number and it changes to an editable box, you edit that and hit return and done.
It would be lot faster in terms of workflow.
