We had this discussion on august: Google indexing
Is there any news of updating the application ?
It’s difficult to work with redesign of live sites, and testing on a copy of a livesite; when you can’t stop search engines from indexing the online version. Which makes it almost impossible to work with an existing site (and show the costumer a live preview).
As mentioned before, MAMP has this as a Standard feature, so it doesn’t seem to be technically impossible.
Are you closer to at solution ?
