I mean the 'Toggle own sort order' option. I think it corresponds to what you mentioned secondly. Actually, I have the first one in mind as well, but that's another topic.
You can check the two topics I opened related to this matter:
Hello,
As it currently stands, when we activate alphabetical sorting for one notebook, it affects all notes within all notebooks. Can we have the ability to set sorting preferences individually for each notebook?
For example, I want notes within the "a" notebook to be sorted alphabetically, notes within the "b" notebook to be sorted in a custom order, and notes within the "c" notebook to be sorted based on the update time. Is it possible to implement this feature?
Thx
