Obsidian / Joplin does NOT support manual / arbitrary sorting of folders or notes

When I finally decided to try Obsidian, I discovered that it couldn't sort folders (except for the default alphabetical sorting). Further searching revealed that most note-taking software (including Joplin) didn't allow manual or arbitrary sorting of folders or notes.

I believe manual or arbitrary sorting is a basic function that any bookmark manager or note-taking software should provide.

Why can't most software do this? Is it that difficult?

Sorting or queuing is a common occurrence in life and work. For example, sorting the exam scores of students in the same grade at a school. Sorting is useful for lists with a few items or a lot of items.

Arbitrary sorting is particularly useful for prioritizing tasks.

Tags are mainly used for identification or grouping, and are quite different from sorting; the two are distinct.

Given the universality of sorting or queuing in real life, I believe it should be a fundamental feature of note-taking software.

I used to use Joplin frequently and hadn't noticed the lack of manual sorting for folders and notes. Since constantly using my own resource management software, I've become accustomed to and enjoy manual sorting, which is suitable for various real-world situations. When I used Obsidian or Joplin again, I was shocked to discover that neither supported manual or arbitrary sorting. This should be a basic feature, yet these two popular note-taking apps don't support arbitrary sorting. I don't understand why they don't. Perhaps their data models, philosophies, or other underlying principles make arbitrary sorting less important or more difficult to implement.
