ghostwriter Portable

Markdown editors have since long been one of the most required tools for web writers thanks to their relative lightness, distraction-free environments and efficient editing and publishing features.
ghostwriter Portable is one of many application of this sort that aims to provide you with most of, if not all, the tools you have come to expect from a full-featured Markdown editor.

Full-featured, portable Markdown Editor

As its name suggests, this is the portable version of ghostwriter. It packs the same features as its installer counterpart while providing you with a bit more flexibility, making it better suited for users who are constantly on the move and have to edit their documents on computers where they don't have full administrative rights.
Straight from the get-go, we will like to point out that ghostwriter has practically all bases covered.

Scores extremely well in the features and customization departments

It has a minimalist, yet very customizable GUI that can be adjusted according to your environment's lighting. It comes equipped with a typical, live HTML preview (which, sadly, is not incorporated into the app's window), a syntax highlighter, live word count, and a useful theme creator.
In addition, you can use custom CSS style sheets for HTML preview, add image or URLs via drag and drop, export your documents to HTML and that's not all. Probably one of the most useful features of ghostwriter is represented by the fact that it provides you with a couple of stylish and unobtrusive, translucent HUDs that bring forward a wide array of useful statistics.

ghostwriter Portable - up there with the best Markdown editors

Taking everything into account, ghostwriter is an interesting alternative to other, more popular Markdown editors. It sports a fair balance between user-accessibility and number of features, not to mention the fact that it is clearly one of the most customizable Markdown editors out there. Best of all, it's portable, so you can take it everywhere with you on any run-of-the-mill flash drive.
