The application basically hides the start bar and all windows, leaving you with just an area to write in, and some options that disappear as soon as you stop moving your mouse.
As a text editor, it's true that Catlooking Writer offers few additional features. You can change the font color and size, and that's about it.
Catlooking Writer is a simple but effective writing tool, especially if you get distracted easily. It's ideal if you want to isolate yourself and just write for awhile.
