I know you can use quickadd, templater or text snippets to make this easier. But I think it would be better if we had a dedicated complementary plugin to the tasks plugin, that works the same way todoist does (we can even use the same syntax).

It would recognize the different properties (start date, scheduled date, due date, reminder date, priority, recurrence), add the emojis automatically and place them in the right order.
It could even provide smart features, like remind me 2 days before, etc.
And of course, an option to append the task in the active file, choose a file or set a file in the settings.
