used original Todoist colors for overdue (red), today (green), tomorrow (orange)
set all due dates to same text size which looks somehow cleaner
last seven days in weekdays are displayed as weekday because it is easier to regocnize than a date, i.e. Friday in red means "should have been done until last Friday"
used more toLocaleDateString options to reflect local date representation, i.e. "May 15" would be "15. Mai" in German (day before months)
set cell vertical allignment to middle in order to align avatar and text
