As Obsidian is all about linking files and making lists there should be a command ‘Sort (selected) lines’ to sort selected lines alphabetically: links, lists, checkboxes etc.
For example:
[[Note taking]]
[[Programming]]
[[Audio]]
[[MIDI]]
or
- first line
- second line
- third line
or
- [ ] task
- [x] finished task
- [ ] another task
- [x] another finished task
