Coders like to use spaces, carriage returns, new lines, tabs and indentation to make their HTML documents human-readable. This helps collaboration and debugging of the HTML document. However, all these features add to the filesize of the resultant HTML document. This structural information is totally ignored by browsers.
This plugin removes spaces, carriage returns, new lines and tabs from your HTML document. You can therefore freely use these features while writing HTML, safe in the knowledge that it will not bloat the final HTML document.
With this plugin you can also mark areas of your HTML template where you want to preserve white space – for example – in areas containing Javascript which needs carriage returns and new lines to function correctly.
HTML comments are not affected by this plugin.

WP-Compress-HTML

Reduces the HTML file size by removing unnecessary white space from the HTML document created by the WordPress blog.

Search Fixer makes “pretty” search links work properly. A pretty search link usually looks like this: 
http://example.com/search/waldo 
Because of a bug in WordPress, pretty search links with spaces in them do not work. Search Fixer fixes that bug.
If you use <a href="https://wordpress.org/extend/plugins/search-meter/" rel="ugc">Search Meter</a>‘s widgets, you should install Search Fixer too.
<h4>Technical details</h4>
The bug is <a href="https://core.trac.wordpress.org/ticket/13961" rel="nofollow ugc">WordPress bug 13961</a>. This prevents “pretty” search URLs from working properly. For example, http://example.com/search/hello%20world should search the example.com blog for the words “hello” and “world”, but because of the bug it actually searches for “hello%20world” and fails to find anything.
When the WordPress bug is fixed (probably sometime in 2011) Search Fixer will no longer be necessary. I will keep Search Fixer up to date so it won’t interfere when the WordPress bug gets fixed.
