I really love this program, but as I use other programs such as Ulysses to accomplish a different set of tasks, I keep thinking that having a sidebar like Ulysses has where all my documents are easily found would make Taskpaper even more powerful.
I understand that TaskPaper is meant to be an editor for the files themselves and that we should keep an agnostic approach to that openness; but honestly, I cannot see myself opening task paper files elsewhere. If this could be implemented in a folder approach in which all my files are still open and accessible, it might become more palatable to many.
