If you’re looking for a quick WYSIWYG editor for html, then Writer for .NET might be for you.
It your regular editor with your usual cut/copy/paste functionality but it can also manage formatting, hyperlinks, and text layout. Just think something like Word editor for HTML but with a smaller footprint, and you’d probably be pretty close to this. Nice thing is that the source code is open so you can basically edit it to your heart’s desire and make it better if you wish. Who said Windows doesn’t have open source?
