You ought to also try HomeSite from Allaire (http://www.allaire.com). It is an HTML editor that really shines in my book. Not only can do tag-level editing (with very helpful help and tag-building dialogs) but if you have IE4 installed on the system you can also do WYSIWYG editing. It can be extended in various ways, (new commands, toolbar buttons, code snippets, tag creation dialogs, etc.) It can do FTP uploads as well as editing remote files as if they were local.
Perhaps building an add-on for HomeSite would be a great answer for the Zope IDE question. Imagine adding a tab to the toolbar labeled "Zope" or "DTML" with a collection of buttons for inserting Zopish things into the document...

Three problems with HomeSite as the Zope IDE that I see: 1) Closed source, proprietary product; 2) Produced by Allaire which also produces Cold Fusion so you're feeding your competitor ; 3) Only runs on Windows. Right now the only reason I have to run Windows is Delphi. I don't want to add another reason <g>. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tom Jenkins DevIS Linux & Samba 2.0 : The best Windows file server http://www.zdnet.com/sr/stories/issue/0,4537,2196106,00.html "Do not be overcome by evil, but overcome evil with good."
