I'm building a replacement for another site built by my previous site-builder app, and realized I forgot to click the "Also add www version of the Domain" before creating the application. so I went back to the application and down to Application Domains at the bottom of the page and clicked Add a Domain button, which let me add www.mouzon.com to mouzon.com.
That got me wondering: is it that easy to create a subdomain? Like images.mouzon.com, for example? I realize I'd have to do Cloudflare integration to manage DNS, but I'd be doing that anyway. I don't need subdomains right now, but it would be great if they're that easy when the need arises.
