Another outliner has apparently bitten the dust. Tree 2 had a somewhat unique function of growing an outline sideways, not unlike Ginkgo. I wrote a review for Mac AppStorm six years ago:

It is no longer available on the App Store and the website is an empty page. Too bad. It was an interesting approach to outlining.

That is a bit f---ing tragic, I must say. I always hoped Tree 2 would evolve into an iOS app. Clearly not.

Let's hope the long-hoped-for Gingko app appears in the not-too-distant...
