I'm hoping you can add a folder feature.

Simplenote currently doesn't have a folder feature, and all notes are displayed at the same level. When I have a lot of notes, it becomes difficult to manage them effectively, and it's also hard to find the specific note I need. Even though Simplenote has a tagging feature, it still can't replace the functionality of folders.

Furthermore, because there's no folder feature, all notes show up directly on the homepage when you open the app. For notes that I don’t want others around to see, this is quite awkward. If there were a folder feature, then for notes that I don't want others to see, I could put them into folders. That way, as long as I don’t open a specific folder, people around wouldn’t be able to see the notes inside.

No files, tests, or entry points are named. Before implementation, define folder creation, organization, navigation, and homepage visibility alongside the existing tagging behavior; completion should cover the requested folder workflow.
