I originally wanted to ask that we be able to sort our Inbox by tag/label. I did see that idea, but also saw requests to sort by star/no star and sender. So I wanted to combine these into a single improvement - to be able to sort the inbox by any column. Being able to do this, helps improve productivity. I would like to be able to see the emails I consider most important to follow up at the top, for example. It can also be valuable to see all the emails from a particular sender or under a specific label grouped together.
