Sorry if this is planned or requested before, but one thing I miss from Notepad++ is a shortcut to open the file in a browser for testing, when doing HTML and such…

Try this out:

github.com/mockko/livereload

Or if the ruby install scares you…

xrefresh.binaryage.com/

Or if that is too much…

livejs.com/

xrefresh sounds great, too bad it doesn´t work yet in firefox 5…
