Changing a block title per theme or page I have a search view, and I use the exposed form as a block to put the search box on every page.  In the block configuration I hide the exposed form block title so that I'll just get the search form with no title.  

That works fine, but now on the Admin dashboard, I want to include the same search box.  The dashboard shows the block title, which is what I want, except the view title is 'Exposed form: publication_search-page' which is gross.

If I try to go into the block configuration and change the block title to Publication Search, I override the  that is in there now, and the title starts showing up everywhere.

How can I change the block title in the dashboard (or when I'm using the adminimal theme or whatever the admin theme is set to if that is easier) without messing up the configuration to hide it on all the other pages?
Here is a per theme solution.
In your View, under Advanced, click on Theme Information, the following pops up:

Now click on style output, and copy the entire code inside in to a new file in your text/code editor.
In my case it is:
&lt;?php

/**
 * @file
 * Default simple view template to display a list of rows.
 *
 * @ingroup views_templates
 */
?&gt;
&lt;?php if (!empty($title)): ?&gt;
  &lt;h3&gt;&lt;?php print $title; ?&gt;&lt;/h3&gt;
&lt;?php endif; ?&gt;
&lt;?php foreach ($rows as $id =&gt; $row): ?&gt;
  &lt;div&lt;?php if ($classes_array[$id]) { print ' class=&quot;' . $classes_array[$id] .'&quot;';  } ?&gt;&gt;
    &lt;?php print $row; ?&gt;
  &lt;/div&gt;
&lt;?php endforeach; ?&gt;

Change the &lt;h3&gt;&lt;?php print $title; ?&gt;&lt;/h3&gt; to &lt;h3&gt;Your Custom Title&lt;/h3&gt;
Then save the file as views-view-unformated--[view-name]--[machine-name].tpl.php
(In my screenshot, example is the name of my view, and machine name is page, basically use last name suggestion)

Put this template file in your Adminimal theme's template folder and clear the cache to see changes.
