3.1 RC2 – Multisite – No site #'s ?

Perhaps I’m missing something, but the site # isn’t visible, unless there is already a domain mapped. In 3.04 it is visible in Dashboard –> Sites, whether mapping is in place or not.

This is a nuisance, as with 3.10 I must open phpmyadmin & find the site number in the tables, before mapping a domain to it.

Is Site # visible somewhere else in 3.10 for domains without mapping in place?

Thanks in advance for any info!
