Ok that's reasonable I guess. You might want to update your proposal as described here:
UX will be very important for this plugin, as it's almost the point of it, so make sure you include some mockups of the UI.
Also try to provide more details when possible. For example "The system will attempt to detect simple deadlines written in notes" - you should expand - what will be detected and what how will that be used. Will the title be updated, or alarm, or tag? All that needs to be described
