Found this little gem. Unfortunately its commercial:
http://www.editpadpro.com/. I am using it for my all my day to day stuff now, It has built in transparent ftp, dom navigation and clip collection, as well as reg exp and so many other stuff! You can even bind scripts and use them on your files while you edit. (this goes beyond things like htmltidy, since you can have whatever you want bound to the editor shortcuts, from a python script, through to a C program).
I think there is a way to use the trial version indefinitely, although the legality would be compromised.
Jedit
http://www.jedit.org/ is also a pretty good editor, and has an ftp module, although unlike EPP, I haven't personally tried the module. Its also free-GPL, so you might prefer it. But boy, does it take a while to load!
Hope it helps!
