Thanks for the comment, that really interesting. First of all, FrontPage is a web-page-editor and html-notepad is not. It means that html-notepad can be used to edit textual content/fragments of web pages, but not the whole page. That's simply impossible. And that's why web-page-editors, as a class, have gone all together. "Sic transit gloria mundi" to them. The only reasonable way of composing pages by pure WYSIWYG means are wizards or page-blocks-composers - something close to mechanism that WordPress is using. "the gap with the ugly rectangles at the left that i'm not sure about" Those rectangles play several roles: a) to visualize hierarchical structure. This helps a lot. At least to predict what hit on ENTER will do. b) they allow to select elements as a whole. In browsers with that "contenteditable" rudimental thing you cannot select whole element: <p>|Foo bar|</p> versus |<p>Foo bar</p>| (where `|` marks start/end selection positions) c) they will serve role of drag handles to be able to reorganize structure interactively. As of UI configurability... it will be there. As of wxWidgets, etc. - I see no reason for that. Neither of popular editors use standard (quite limited) OS widget sets. MS Office, Adobe, Sublime and so on as examples.
