I am using the UW now as my default upload tool and I like it more and more, even now as "Commons power user".
I suggest to add user preferences for some fields:
- Information template:
- license template
Maybe other fields too, but above are my typical needs, see https://commons.wikimedia.org/wiki/File:Wilhelminatoren_Valkenburg-2490.jpg for an example how I use these fields.
