Just going to voice my preference — I'm looking for the code to do this — for having handles always show. The reason is simple, but is not illustrated above. The handle allows one to instantly tell if a line starts (what I'll call until I know better) an outline Item or is part of but not the start of a multiline outline item.
I am an inveterate outliner, and I write long notes. I also frequently show my outlines side-by-side with other program windows on my primary computer, which is a 15" MBP. Each of those, especially partnered, means I regularly have outline items that wrap to multiple lines. Not being able to instantly visually distinguish between an item with no children (a "leaf", I think this called here and in the code) and a line of text that is part of an item's text that has been wrapped, regularly brings my work to a halt as I have to stop and ask "What is that?"
I should add that I am looking into using TaskPaper for much more than just a Reminders replacement. (And maybe FoldingText is better suited, but TaskPaper was more recently updated and seemed much more likely to continue to be supported.)
Sorry for bringing attention to a dead thread, but I thought it worth indicating the need that you so pinkly dismissed as unneeded.
I think I'm close to finding an answer to my question, but ... is there a way to turn on leaf handles? I realize I can color them using the code Jesse cites above, but I'd prefer to have them inherit the standard handle color of the theme (and change as that changes). Thanks.
