I feel the same about this - my hour on google didn't bring about any such thing we both might have missed... I use Evernote to keep track of todos, so i imagine it to be so much more powerful to just hit cmd+ctrl+N at any given time to quickly punch in a task as it comes along and have it sorted to the right list without any further steps necessary... As you put it so nicely: we can live in hope... cheers!
..totally second this request! have been searching for this on the web for a full hour or so, it would make evernote helper the single most powerful gadget on my os!!!
