tuning plugin?

I've been messing around with the tuning plugin that comes with MU for some project.

I'm not sure if i'm missing something but the annotaions option doesnt seem to add any text to my score. Are they being maintained by anyone? I couldn't find them in the plugins page to check if there is an updated version.

I also found no difference between the "tuning" and "Modal temperaments" plugins. Why were they not combined into a single plugin? they basically are the same plugin with different temperament list.
