Scid vs. PC Question: ECO Codes

According to the documentation, the ECO Browser window should have an "ECO Classify Games" button which "will permanently add ECO classifications to selected games in the current database."

Here's what my ECO Browser looks like, with all the games selected.

I'm able to add ECO codes to my games one by one, but it becomes tedious if I'm importing many games at once. Does anyone know where this button is ("Update" isn't it) or if there is an alternative way to do batch classifications?

Ok, the doco is a little outdated, which i will update.

The feature/ button is still available, except it is now only in the maintenance window.

Yes! I see it. Thanks for being a responsive dev!
