Metrics Machine Reference Groups

[jmickel]

Hi Frederik,

I'm noticing that the Metrics Machine extension does not support reference groups.

Are there plans for implementing support for this important feature?

Traceback below:

Traceback (most recent call last):

All groups except pulic.kern groups should be shown in the reference group editor.

Was this possible in the UFO2 version of MetricsMachine?
Is there a traceback?

Thanks Frederik! Works great.

I noticed one other thing: it's not possible to copy reference groups using the import feature in the Reference Group editor. Only the public.kern groups show up.

I can copy Reference Groups by editing the groups.plist, but that's not ideal.

I’ve just fixed this, please update Metrics Machine with Mechanic.

thanks!
