Along the lines of cruft-free URLs, I would like to see an option to set a custom "album slug", which would appear in the URL. It would be nice if the default was the title of the album itself rather than the folder name (as it is now).

The album 'slug' is the folder name, pretty squarely. Would it be adequate to allow folder renames that don't botch the database? I think that would give you the functionality you're after...

That sounds like it would work just as well. I suppose that your alternative is planned?

Of course :-)
