For many years I used the regular notepad and it served me quite well. In the days of the 3.5″ floppy I remember have cases full of html codes saved. It saved time to write or find a particular piece of code and then just keep it on a disc for when I needed it. Notepad was easy because when you copy and paste from it there is no coding that comes from it, only the text of the code.
I was introduced to Notepad++ about a year ago and I have to admit that I like the ability to tier the code. Also the text auto-coloring for particular tags allows for quick debugging. The GUI reminds me of Matlab, which I have used in the past. The only problem that I have with it is that the spell check is in the Queen’s English so many of the corrections are not wrong in American English. Other than that I would recommend it to anyone.
