What would be really useful is also having shared functions across formula fields. That would allow to overcome current UI-level limitations of presenting data while not requiring creating redundant formula-level piece of functionality over and over like this one:
ToText(Year(Deadline)) +
If(
Month(Deadline) < 10,
"0" + ToText(Month(Deadline)),
ToText(Month(Deadline))
) +
If(Day(Deadline) < 10, "0" + ToText(Day(Deadline)), ToText(Day(Deadline)))
just to show date with leading zeros.
