Google usually makes good stuff, but I only had problems with it so far.

If I understand right, this is how it goes:

- I own a site or domain

- I add site to my Dashboard

- I verify site by uploading a file to the server or add A record in domain's DNS server

- I can do a lot of things with my domain, see search queries, who is linking me, etc.

Everything is simple to point, where I don't want a "disk space wasting" file. I just want everything tidy and clean, so I always delete unnecessary data/code/files. But if I delete this thing, then Google says that my website isn't verified. WTF??

Can't Google remember, that it had verified my site already? Cause I don't want to go trough all of these steps to verify my site again, every time I use webmaster tools.

Apart from this, Webmaster Tools have other problems too. For example, you cannot use "Change of address" feature with .eu domains. What's wrong with this TLD, Google?

Why the heck do I need to verify www and non-www address? Isn't that the same thing? I know that you can have different content on those two subdomains, but still ... who uses that? The best practice is to redirect it to one or another, this is good for SEO too.
