Has anyone figured out if there is still a way to update the metrics via the Font Properties tab - what used to be the Calculate button?
The calculate buttons are not available yet.
We intend to release an update later this week, coming with a single calculate button which will calculate and set the metrics for all masters.
Here is a release that comes with two Calculate buttons used to calculate values for metrics for horizontal writing mode. The values will be calculated for all masters.
