Ultimately. I do need to see what does and doesn't work with MZ and why. Dualtechs surprised me by working fine without updates - the MZ version of the Dualtechs plugin just takes the "turn linking" functionality that previously required other plugins and adds it to MZ's ATB mode.
I haven't gotten to this plugin yet outside the FOSSIL test mentioned above, but I wonder if the subtitle window will be the only concern.
