Yes! That is exactly the kind of feedback I want.

I'll have to give it some thought though. I hadn't given any consideration to doing an horizontal view yet. I like it as a differential feature to what other outliners are doing.

I have quite a few traditional outline functions that I want to implement first. Hoisting and scripting/automation are at the top of my list right now. I don't expect that I would be able to implement a new big feature like this for at least another year.
