Many programming flaws!

Finally, a couple of months ago this app started working on MacOS Sierra. That is the reason why I am changing my review. The new version, however, has many programming flaws. One example is that all my favorite colors are gone and I only have “color 32” available (and I have 50 of the same thing). It won’t rename it, it won't change the color, and it won’t even restore to default! I have sent a report on this with a screenshot to developers to no avail.

by far the most powerful outliner

I've been using Neo for several years - since before it was called Neo. It is immensely powerful. It much more powerful - and much much cheaper - than the popular alternative.

Neo has a few interface oddities/annoyances, and the documentation is not very good. So recently, I downloaded the better known, more expensive outliner, the pro version, and took it for a drive. And I really wanted to like that alternative -- they have good documentation and I like their other software.

Neo blows it away completely. I want what Neo can do. The other is just too limiting -- even their pro version. So I'm back. [Ok, I never quite left, but you get the point].

You are definitely driving with a stick with Neo, though. So if you prefer an automatic transmission, if you need some handholding, and if you can live without a lot of power, then Neo is not the droid you're looking for. Pay a lot more and get the other one.

But if you don't mind extra work at the beginning and if you can figure things out on your own -- you can't beat Neo's power, or the price. Please buy it. We need to support this guy.

Powerful outliner

Very powerful, steep learning curve. Has been updated continuously for years and years and years while others come and go. Great product, esp. once you invest the time in learning it. There are other outliners that are prettier, but I’ve yet to find one that is more powerful and feature rich. I do wish the Word export came out as an actual Word outline.
