Just some terminology: since version 1.5 WP uses themes that are made up from several templates. If you are a visual type see this anatomy of a theme. It is not an index file… it is several files working together.
When editing WP template files – I wouldn’t use DW.
And you can use any theme you like, most of them you can modify to your needs, or you can make your own. (Worst case scenario: you can hire somebody to make a custom theme)
I’m confused about single.php. Does the Kubrick template have limited functionality? Do the other templates available at http://wordpress.org/extend/themes/ offer more functionality?
I wouldn’t edit the WP template files with DW. I would only use it to create my own index.php template file from a copy of my homepage.
If you took a look at my “anatomy” – you should be able to understand when and the single.php is used.
Nobody said Kubrick theme (not template!!!) has limited functionality. On the contrary… sometimes it’s too much for beginners 🙂
And again: one index file is not a theme > see more: Using_Themes more details > creating themes.
