EditPad Lite is an excellent general-purpose text editor that's fast, easy to use, and packed with useful features.
The program can open as many files as you need, for instance, and you can switch between them with a tabbed interface. The tabs work much like a browser, so you're able to rearrange them by dragging and dropping, close all but the current tab with a right-click option, or save a file by dragging and dropping its tab onto a folder.
EditPad Lite offers a wide range of interesting text manipulation options. You're able to indent and outdent text, insert the contents of a file at a given point in your document, convert a selected block of text to upper or lower case, and more. A powerful search and replace panel includes a history, so you can recall previous searches in a couple of clicks. And the unlimited undo and redo will rescue your work if you make a mistake.
The program can handle documents with Unix, Mac and DOS line endings, and supports Unicode text files, all Windows and ISO-8859 code pages, as well as many DOS, KOI8 and EBCDIC code pages. So no more editing complications, just because you're working with a file that came from (or is destined for) some other platform.
Productivity features include the option to keep the EditPad window on top of your other windows. And the program can leave an icon in the system tray, so it's very easy to access. But if you don't like that, then it's easily changed, as is just about every other aspect of the program - it's all extremely configurable.
