I think it would be a great QOL to be able to quickly see a list of all tasks due within a certain span of time. I personally would like to see all tasks due within a week, but I could envision certain workflows wanting within a month or a more arbitrary date range.
We can already see a list of tasks that were due in the past and a list of tasks due today on the side panel. (See the attached image). However, in order for me to see what is due within the week in order to schedule my week—or just have the tasks in my mind—I have to open each task list separately. This could make it easy to miss a task on accident until the day it is due.
I'm coming from Amazing Marvin which has a feature called "Smart Lists" (https://help.amazingmarvin.com/en/articles/1950204-smart-lists) where you can choose very specific filters that create the list. Amazing Marvin was over complicated for my needs, and I am loving Morgen, but this use case of smart lists (listing tasks due within the next week) is sorely needed for my work flow
