Visual Option to Hide Checked List Entries

Use-Case

As other people already said this feature is extremely useful for organizing to-dos
like shopping lists because you don't get distracted by already completed to-dos.

Tasks?

Tasks are fundamentally different in what there intended use is impov:
Tasks are reminders for deadlines or independent tasks much like "zero-time" calendar appointments.
Additionally, it's much harder to manage a group of to-dos in Tasks and format them a specific way
like subgroups representing departments of a supermarket or link additional information comfortably.

• #1274

The above two are currently stale because, as for my understanding,
don't meet the following requirements:

1. No modification of the notes.
2. Don't assume semantics of notes.

Suggestion

Add a visual only option to hide list entries with checked checkboxes.

Example

# Q's
- [x] Qux
- [x] Quux

# Misc
- [ ] Foo
- [x] Bar
- [ ] Baz

This markdown note would be rendered with the visual option enabled like:

Q's

Misc

• Foo
• Baz

As soon as one would check the checkbox of Foo it would result in the following render:

Q's

Misc

• Baz

With the visual option disabled the final markdown note would be rendered like:

Q's

• Qux
• Quux

Misc

• Foo
• Bar
• Baz

Start by tracing the note-rendering and checkbox-handling paths, then read related issues #681 and #1274 for prior constraints. Implement the option as visual-only behavior: checked entries disappear from the rendered view while the Markdown remains unchanged, and unchecked entries remain visible. Verify the example transitions with the option enabled and disabled.
