Hi
From the first day, I liked org-num-mode, but I think that its default which numbers all headlines could be problematic.
Right now it only has the options
to exclude headlines from being numbered, so it could be
necessary to modify a big amount of headlines, for numbering
just a tree.
I think it would be helpful to have a "positive" way to numbering headlines, for example "NUMBERED" keyword, while all the other headlines stay unnumbered.
