Datj Vid on "The new update WordPress 3.5.1"

I think the team of WP is doing quite an elaborate updates.
But if you ask the users of WP like me, who is running around 10 websites on paid servers with WP, then I will say that the users of WP like to have a thorough offline environment just like Windows live writer.
If you recall the creation of website and publishing it on the server using MS Front page, you will understand what I mean.
Every piece of information of my website is also available on my PC also, when using FP.
I may be rather ignorant about the development about WP, but DOES WP AT ALL HAVE SUCH FACILITY, ALREADY FOR THE USERS LIKE ME....?
Please reply anybody....!
Thanks in advance...
