I support this request.
It was unexpected that having the options to choose date format, for Daily notes and Unique note creator core plugins, then I can not use that easily for plugins or in date/time properties. I have to use
to keep the picker functional.
If I had been aware of that information beforehand, lots of related issues could have been avoided. I think it isn’t on https://obsidian.md/help/ either, can’t find it.
