tl;dr - Unique Note Creator (initially a zettelkasten feature that came before in beta) could optionally insert the unique identfier code into Properties rather than the note title, for users who don’t want to, or are unable to, add Community Plugins to their vault, and would like the Title to be human readable text, leaving timecodes usable but in the note’s metadata.
The feature was modelled after Niklas Luhman’s indexing system for his zettelkasten notes (which was a string of numbers and letters), resulting in the acceptable solution to be to have a title made of, or prefixed by a string of numbers or a date/time code.
For most users, this is likely not very human readable - and since Bases has been introduced to Obsidian, this unique identifier could optionally be added to Properties (yaml frontmatter) for a host of different uses.
The note’s title is already a field that can be used in Bases, so this feature wouldn’t add usability there, but as a quality of life feature it would allow non zettelkasten uses requiring unique identifiers for notes where users want simple text titles.
Proposed solution
“Unique Note Creator” settings to create a note with the unique code (however the user has formatted it) to be added to a “unique note number” Property in the note’s frontmatter.
Current workaround (optional)
There are a number of Community Plugins which are enabled to edit notes, and add in javascript (e.g. Linter, Templater, etc), but not all users are able or want to expand their vaults to allow that.
