Not too horrible, though changing the 'local server' port to 8080 and then launching a script still attempts to load at port 80. The program doesn't insert the port number into the URI. I love the vertical line drawn at column 80, gives a nice visual for when you should start wrapping your lines (though technically speaking, the row/column positioning in the left hand corner is enough to get by). All I'll say is that at this point I wouldn't pay money for this tool as it doesn't offer anything more that the free tools already do.
