Screen Options on edit screens

[janeforshort]

The screens with lists of items (edit posts, media library, etc) look cluttered with every option shown. We'd originally talked about putting options to hide some of that stuff into the Screen Options tab so that people who don't use various things wouldn't need to have them clutter up the screen. Can we put any/all of the following items into the Screen Options hide/show function:
-Search
-Filter by [date, category, whatever the menu options are]
-Bulk actions

I don't think we can leverage the existing meta box AJAX and JS for those, so let's postpone.

what's wrong with being able to search / filter by default?
