Mastermatic has been updated to version 2.4.0.

A scrollbar now appears to the right of the paragraph-styles–master-page list if there are too many pairs to fit comfortably on the screen. This means that there is no longer any limit to the number of paragraph-style–master-page pairs you can add.

Additionally, as with all our other scripts, we are moving away from serial-numbers, as it seemed difficult for many to keep track of their serial number. Moving forward, all products can be activated simply by entering the original purchaser’s email when asked.
