We all like notepad since it is quick easy and very lightweight. But what if it just does not do all that you want? Well I have used programs like Ultra Edit and I love it. The downside is that it is not as lightweight, you have to buy it, and the intallation is a pain. Great App and it does just about anything that you could wish for. I have found an alternative to this though. It is lightweight, free, and install could not be more simple. It is Notepad++. This may not have all the features of Ultra Edit and other programs like that but it can do so much. Multiple tabs, text highlighting, great search and replace, and if a feature that you need is not there then you may find a plugin for it. Like I really like the compare feature of many editors and this did not have it. I was able to get it though. Just download and install the plugin and you are ready to go. If you do not see a plugin that works for you then you can write it. I love that. I have not done that but I know I can try if I need added functionality.
