This outliner does a fantastic job of replacing my former outliner-and I have more options than with my old app. The combination of auto-numbering and choice of colors to add to my entries helps me keep my thoughts straight & my outlines uniform.l I also appreciate the ability to move my sub-tasks around without switching modes, as was the case with my former outliner. I believe its that, along with the option to have a (very nice looking) dark background & color options that I appreciate the most, though. Its much easier on my eyes and much better looking than dimming a white screen. My eyes are very sensitive to light, and are actually relieved when I work with this outliner. The font size & style choices are also helpful, as with a small, bolded font, I can see a lot of my information at once, and do so comfortably. Thank you for this outliner, its a great app. Id recommend it to anyone.
