another one ... is phped :
www.soysal.com/PHPEd/
i like this. it lists all your classes and functions on the sidebar too. a list of pretty much all such editors is found :
www.itworks.demon.co.uk/phpeditors.htm
and a good friend you may enjoy is called webdrive , at :
www.riverfrontsoftware.com/
webdrive basically creates a network drive as ftp. makes your webserver look like another HD and has nifty little intuitive features, it's a good replacement to homesites somewhat weak ftp capabilities as well. worth a look, very very nice.
