ATR, for the next version of this pack you could use the trick found out by Captain von Keldunk, which allows the US and german crews to actually use different voices without any need to switch voice packs with JGSME. It works by splitting the number of voices in two, making one set be german voices and the other american voices. Then, the text file for the voices is edited making german crewmen only use the german voices, and american crewmen use only the american ones.
IT reduces the number of different voices available to half (And also the download size, obviously), but in my humble opinion

it is worth it for those who switch theaters frequently.
A guide to that fix can be found here:
