ConstEdit is a word processor designed for ease of use. Unlike cloud apps and online html editors, it does not require an internet connection to work with. It runs locally on your pc for better performance, convenience and security.

By omitting functionality that is unnecessary for the average office requirements, the user interface is kept clean. The editing functions are sensibly arranged across the toolbars and the right-click menu, making them directly and quickly accessible. The sizes of the toolbar items auto-adjust to always fit the window width so that you can find the same item at exactly the same location, irrespective of the app window size. Extensive pop-up tips are provided to help you get started quickly. Document authoring is intuitive with ConstEdit.

Because the created documents are of the standard internet webpage format, you can now write your own webpages even without any prior knowledge of html coding.

Features comparison between ConstEdit and regular word processors

Support of "section" (this is the common understanding of section in a document, i.e. a portion of the document content, not the section that defines the beginning of some page formatting style as is quoted in many word processors)✔ ConstEdit uses the common understanding of section, which is independent of the styles formatting of its content.

✔✘ The scope and the level of a section in most word processors is implied from the heading style that is applied to some text.

Insert section✔ In ConstEdit, the action is very intuitive : select the "Insert Section" item.✔✘ Not intuitive : you choose the heading style that corresponds to the section level.

Format copying
Separation of content and layout / styles formatting✔ The styles formatting of the whole document can be changed by simply applying a different stylesheet. The content and document structure are not affected in any way. Styles formatting is not "burnt" into the document content. ✘ The styles formatting is "burnt" into the document content. Changing the styles of the content can even affect the document structure.
Automatic styles formatting✔ Styles formatting is done automatically according to the stylesheet that is applied to the document. Element types (section, sub-section, heading, paragraph, bulleted list, numbered list, etc) are styled to the desired look on-the-fly automatically while these element types are inserted into the document. You can concentrate on the content authoring part.✘ In most conventional word processors, styles formatting must be done at the same time of content authoring. You need to specify the styles explicitly and repeatedly to give the document the desired look because content is not separated from styles formatting. A large portion of the effort of writing a document is spent on styles formatting.

Most of the html functionality of ConstEdit is based on the technology of XULRunner from Mozilla Foundation, which is the same technology behind Mozilla Firefox. The unmodified XULRunner runtimes are bundled with the ConstEdit installer and is placed into the installation folder.

If you would like to take a look into XULRunner, you may go to this link http://ftp.mozilla.org/pub/mozilla.org/xulrunner/releases/. The runtime, sdk and sources are all available there. During the development of the interfaces to XULRunner, reference was made to the Geckofx project.

Please note that ConstEdit does not require Firefox to be pre-installed on your pc to run properly, and ConstEdit will not install Firefox on to your pc during its installation.
