- You can add, delete, or rename notes outside Dendron. If Dendron is running, it watches for file changes to detect these. If Dendron is not running, it will read all the files at startup and see the change. The only caveat is that existing links won't automatically update like when you use the rename note command. - You can change note IDs as well. The only requirement is that they have to be unique, so something like nanoid or UUID works well. It's also recommended to use ids that are "url safe" because they are also used in published website urls. File names are used for the hierarchies. Note titles are cosmetic, it's just like adding

# title

to the start of your note except that it's used in a few other places like published page titles and link titles. Note IDs are used to uniquely identify notes inside Dendron, a lot of code uses IDs to say "this note exactly".
