configurable/scalable cards

[ChaosNicro]

I found this as a foss-alternative to "how long since", which is a datapoint tracker plus the days-since-statistic.
Since the tracker card only shows the last timestamp, every tracker in this fashion needs a 1x1 card for itself and a 1x2 card for the statistic. Which doesn't align well.
It would be cool to have a 1x1 version of statistic- or group-cards. Alternatively, maybe you could set a statistic to show on the tracker card instead of the default look.
