Speaking on www-Sharp IDE, Im in a big trouble. Not because the software is bad or strange; its just the other way around: it has so many of so well designed and coupled capabilities that I still cant believe all of that is real. But it is!
Look here: www-Sharp is a tool for the client-side and/or server-side Web development, AS WELL as for the development of HTML-based standalone applications (HTA) and .Net applications.
The software has HTML and XML editors, with equal grace running in the visual or text design modes. For the HTML editor, there are even three modes: raw HTML, visual design, and DOM tree-level editing. www-Sharp also has editor modes for CSS, plain and rich text, PHP and Java, Perl and C#, and much more. There is also a console for the immediate interpretation of code snippets to review the output.
With www-Sharp you can compile HTML Help files, HTA standalone applications, even .Net assemblies! For your applications, you can utilize www-Sharp.Runtime, which allows using server-side technologies (ASP, ASP.Net, PHP) in plain HTA applications on any computer.
Being a real IDE (*Integrated* Development Environment), www-Sharp *integrates* many useful tools you may need in your work. From within the software, you can work with WMI, databases, Active Directory, review COM typelibs and .Net assemblies installed. And all that is inside one slick handy application!
