Replicating your config on your sandbox
It would be great to be able to replicate your environment in your sandbox. There is an export facility in the prod box, but there is no Import facility. Having a sandbox that doesn't mirror your prod box is pretty much useless, and having to redo all the config manually on the sandbox is extremely time consuming!!!
This is the first thing that any customer with a sandbox will be asking for.... and I'm probably not the first one!
