Adventure (full name: Adventure IDE, formerly called AutoGUI) was originally an IDE designed specifically for AutoHotkey that combines a script editor with a GUI designer, debugger and tools. It is as easy to use as Notepad, and it is both an editor and a structure library, function library, and script library. Once you become proficient, your original development efficiency can be greatly improved.

As another excellent one of numerous alternatives of Windows built-in Notepad, EditPad supports almost all the text editing tasks. It has two editions - Lite and Pro, the former is for individual users and free to use, the latter is tailor-made for programmers or other professionals which is commercial.
