Yesterday I tried the .htaccess editor it was a great design. I simply uploaded a index.html file there then redirect visit from the root to this blog.
Under Web Site Tool there is also a Index Manager which is very handy, just by clicking I turned off indexing of a directory such that people can't hack into the directory structure of my domains.
There are also some very useful things there such as File Manager (not much explanation there as to what I can do or shouldn't do?) and Custom Error Page which I will surely try out later one.
DreamHost? They have nothing like that and if you mess around you'll crash your sites unless you are as good as their tech support.
