Got into the preview, can finally search for actual code! One thing I'd like to see, though, is the ability to mark directories to be ignored in the search results. No one needs to search the raw HTML of my generated documentation, yet it shows up in every search for project symbols. And since HTML is considered "source", I can't filter it out unless I select a particular language.

Also the search text field is bit messed up in Safari when the text gets longer than the field.
