I don't know about others but I would appreciate a .htaccess file in the zen folder. The default Apache setup will allow for Indexes of the zen folder under some setups, such as my host (DreamHost). I added one myself, very simple at that.
I don't know if others consider this a good idea but it's a relatively easy addition that makes things slightly harder on those would would like to attack my site.
Thanks for the great software!
