I’m using TB also as an outliner for a large document of mine and face the following usage case which I illustrate below in simplified form. My aim is to keep very close the ideas, draft text and finally the good quality (e.g.) reviewed text so that I can quickly go back and forth and update accordingly while keeping in mind the structure of the document.
In the general the hierarchy will be complicated with various subheadings going to a depth of up to 4 levels. My question is how best to for instance only part of the hierarchical tree (e.g. only the ideas for each chapter, subchapter etc… or only the draft text + good text to check whether I captured everything) ? NB that the illustration is a visual representation of a very simple outline. I mainly need this capability in outline mode.
