Suggestion: "Move As" dialog expands to width of file name

I'd like to be able to see the whole file name when editing in the "Move As" and "Copy As" dialogs.
Either that, or show the whole name during inline rename (even in "List" view mode).
I save a lot of web pages, and almost always alter the beginning of the file name and remove the web site name from the end.
This would be faster/easier if I could just see the the whole name at once.
