Isn't it a pain when you have dozens of Views setup and they are all marked as "overridden" because you just pulled in an updated feature file from somewhere. Features doesn't always notice when the Views on your site aren't up to date. The following snippet (which you should use with caution) will batch "delete" (or Revert, once the view is in code) all Views which are marked as Overridden.
Views Display Tabs exposes the displays of a view as tabs, making it possible to switch displays for a view using AJAX. This opens up the possibility to make a view even more useful as all overridable settings for a view can be stored in a display. This means that sorting, among many other settings a display can have, can now be exposed to the user through multiple displays with different sort settings.
The Table Wizard facilitates dealing with database tables: It allows surfacing any table in the Drupal default database through Views 2. Relationships between the tables it manages can be defined, so views combining data in the tables can be constructed.
Provides a views filter that sorts titles by a more natural manner by ignoring articles like "The" and "A."
custom field to your Views—markup, PHP, or row number
We use the Views UI a lot to create custom pages, blocks, etc. Sometimes it does not give us exactly what we want and we would like to modify the generated sql query. It's possible to achieve this through the 'views_query_alter' hook.
