I'd like to make a couple of suggestions:
When some files have been successfully updated the page gives links to either the skin submission page or the log-in page. It would save some time with multiple update submissions if there was a link to the skins update page as well.
Are you talking about the link from the "Updated" panel, which currently points at the released skin?
If that is the case, that is a bit of the problem. The "updated" information is not really there. In order to make this work, the utility creates a pseudo submission which has no link to anything in the system (not even in the database) as I have to manually create a lot of things in order for a skin update to really happen.
Basically, it has to do with what happens in the background, which is rather extensive to update a skin in the game.
While we can update all the files for a skin now there is no way of adding or editing the history text as you can with a new submission.
I can add the text information text field to the update list. Give me a bit. It is a little more complicated for that one.
The name of the skin will never be available for updating.
