The ability to group by due date in List View is helpful. However, it's not helpful how it doesn't group future due dates day-by-day beyond 6 days into the future. For people who are tracking deadlines where it's important to stay on top of them more than 6 days in advance, this is a huge limitation.
I assume that the reason it goes until 6 days may be for clarity purposes. Because the groupings are labeled by the day of the week and if today is Thursday for example, and it had more than 6 days, the 7th day's grouping would be labeled "Thursday," and the 8th, "Friday," which would also be tomorrow, etc.- I could see how that might get confusing. However, this confusion could be easily avoided if beyond the 6th day perhaps, it used a different date format. I think Long date would look better personally, like May 18th, 2023, or Thursday, May 18th, 2023.
Either way, I just think that all tasks that are due more than 6 days in the future being lumped into a big "Future" section, is not useful. I think many agree, in this post, https://clickup.canny.io/feature-requests/p/group-by-due-date-beyond-tomorrow. I wanted to my own post even though the topic is similar because I didn't think it captured exactly what I wanted. It's also from 2019 and didn't seem gain as much traction as I think it should.
