If there’s a feature I feel Dynalist is missing, this is it.
I don’t know how familiar you folks are with Emacs Org-Mode, but there’s a function called “Refile” that allows you to, well, re-file one heading under another one.
Going back in time, there were the good old MS-Dos based outliners which usually had some kind of feature for marking multiple list items and moving them to a different heading, or even a new heading.
This would be useful in a variety of scenarios, for example, having an Inbox heading in a task list with incoming tasks and be able to move them to a their proper project heading (or create a new project heading) later.
Or in my case, I love this functionality and still playing with ye olde outliners because it’s so good for doing stream of consciousness writing/brain dumps and making it coherent later.
