Ok this is really easy but i have seen people asking how to do it

1) Download a clean copy of phproxy PHProxy | Get PHProxy at SourceForge.net
2) Open index.php
3) Scroll down to line 1142

$_url_form = '<div style="width:100%;margin:0;text-align:center;border-bottom:1px solid #725554;color:#000000;background-color:#F2FDF3;font-size:12px;font-weight:bold;font-family:Bitstream Vera Sans,arial,sans-serif;padding:4px;">'
4) edit colors, sizes, etc.


1) To edit the URL text bar scroll to line 1144
and edit this
<input id="____' . $_config['url_var_name'] . '" type="text" size="80" name="' . $_config['url_var_name'] . '" value="' . $_url . '" />'
and next to input paste style="width:200px"

2) to make form scroll when you scroll add this to url_form div style (line 1142)

(change top and left % as you like)

This is just a draft you can edit it the way you like, play with colors sizes, transparency.

Good luck
