Exactly what I was looking for.

I have missed a program I used to use on a PPC for years. Its finally been implemented for iOS, and its dreadful. I’ve been in mourning. Then I discovered CarbonFin Outliner.

THIS is the program I’ve needed. Clean, straight-forward, does the job handily, and pretty sweetly intuitive. Well done. Worth a lot more than developer is asking.
