Have you ever just wanted to open a code file real quick, but notepad just doesnt cut it; I have. I frequently open .cs, .css, .aspx, .config, etc files just to make quick changes to them or to view their contents. Unfortunately opening such a file using Visual Studio or Eclipse takes a little while especially if all I want to do is peek inside the file. Using notepad is just plain BORING because there is no syntax highlighting, no line numbers, no code colapsing, etc. Well, I recently found a nice little notepad replacement tool just for Coders called "Programmers Notepad."
Here is a screenshot of Programmers Notepad modifying a Perl file. As you can see it has code colapsing, line numbers, etc. One thing you dont see from the screenshot is that Programmers Notepad has autoComplete functionality built into it.

Programmers Notepad comes with many different Syntax Highlighting schemes including but not limited to Perl, C#, CSS, C/C++, HTML, Java, JavaScript, Lisp, PHP, Powershell, Python, Ruby, SQL, Visual Basic, and XML. I will be adding this Application to my Toolbox.
You can get your copy of Programmers Notepad at http://www.pnotepad.org/
Overall, I would give this application 8 out of 10 stars.
