🔖 Feature description

The obsidian reminder plugin uses ⏰ for reminder dates.

✔️ Solution

It would be nice to have ⏰ included in the tasks autocomplete menu.

❓ Alternatives

No response

📝 Additional Context

It would probably be good to have to turn this on explicitly through the settings page so that people without the reminders plugin don't use it.
