Partial Habit Quantities & Different Units

My simple goal is to track hours of sleep. I don’t just want to have a „sleep 8h+” because what if I sleep 7h40min?

That’s not quite 1, but it’s definitely not 0.

But for example, I can’t enter 7.4h, which isn’t even 7h40min - 7.66 is; which feels very unnatrual.

For that reason, I’d love to be able to log partial, quantity-based habits + be able to log it as time (that divides by 60 and not a 100) and by other common units.
