My point (and I was being a bit snide, sorry) was not that you haven't been clear enough - anyone who needs a picture to understand the end result hasn't been paying attention while reading - but that I don't count it as "inbox zero". It feels like cheating, like saying "here's how to completely clean all of the rubbish out of your living room: dump it in the kitchen".
Yeah I definitely don't have a perfect solution for this. Sometimes it piles up. One thing that I have found effective is having a designated end of day "clean up to-do list" time. Definitely open to hearing what you think would be a good solution.
