More priority options and auto emailing changes

I’d like to see a feature that allows for more levels of priorities (at least 1-3) so that i can sort by priority. I like a lot about nozbe but Todo now syncinging on line and ipad has some of these layering and “Focus” features that helps. Can you work on those? Also, the best thing would be when we have these team projects, if when changes were made, they were highlighted for 24 hours and you could subscribe to a “change/update” email daily that shows what things were added/completed/commented. That way it’s sent straight to me instead of me having to check. A Push feature for this on the ipad would be great as well. thanks
