Serif WebPlus Alternatives with feature 'WYSIWYG Support'
Serif is a graphic software developer with a rich history of excellence in design and WebPlus is part of that history. It's now discontinued, but the drag-and-drop website creator provided a very intuitive way to build sites visually. Fortunately, there's now no shortage of similar visual design apps.
Arguably, the most relevant feature would be a wysiwyg-editor since WebPlus was all about visual design. While many modern tools are online, there are some great desktop apps for Mac, Windows and Linux.
