[Plugin: Better Tag Cloud] Improvements Can Be Made

The following improvements can be made :

1. The Settings tab is ignored in the latest versions of the plug-in, and should be removed altogether to avoid confusion.

2. The font sizes inserted in the HTML code contain way too many decimals (ex : 4,33333333333333px). The round() function should be used :

$tagsize = sprintf ( round( $smallest + ( ( $count - $min_count ) * $font_step ), 1 ) );

3. When nofollow is enabled, the plug-in generates invalid HTML code, according to the W3C Validation Service. Why ? Because nofollow inserts a rel tag :

rel="nofollow"

but such rel tag already exists and should be removed :

rel="tag"

4. When nofollow is enabled, unnecessary spaces are added. Line :

$echo_nofollow = ' rel="nofollow" ';

should be :

$echo_nofollow = 'rel="nofollow"';

5. When replace is enabled, the plug-in replaces spaces with nobreak spaces, but it should also replace hyphens with nobreak hyphens :

if ( $replace == 'Yes' ) {
			$tag_name = preg_replace( '# #', '?', $tag_name );
			$tag_name = preg_replace( '#-#', '&'.'#8209;', $tag_name );
		}

6. Tags with accents (ex : é, ?, ?, ü) are not sorted correctly. A user named “Emilio” already provided a solution on the plug-in homepage.
