Almost all web publishing tools on the market use so called WYSIWYG (What you see is what you get) editing where you edit the content of the site by navigating thru an administrative interface to the page you want to edit and then click on a button to open the editor which looks like a simple version of Microsoft Word. But because the editor is opened in a complicated application interface you will only get a vague idea of how your content will actually look when it is published on your website. To actually see how the finished website will look you then have to save and close the editor, and click to open the site in preview mode. If something isn't right or look quite the way you want it to, you have to go back in to the editor, make the new changes, close it and go back to preview again.
What we have done with SmartCMS is to remove all of the complicated technical interface and preview mode and instead incorporated all of the editing directly on your website. That way, when you update and edit your site you will always see exactly what the finished result is going to look like and you can easily and quickly adjust and modify the look and feel of your content until it is presented in just the way you imagined. If you want to edit a text - click the text and start typing. If you want to change an image - click it and select a new one. It can't be any more simple.
