Hi! As we said, we were reading for your suggestions on future content packs, and we found a bunch of interesting ideas!
We've created a poll with the ones we found most interesting, so you can vote on the ones you prefer. Note that creating a content pack takes time, so it be a couple of months at least until it's ready.
Also note that while the most voted is the one that will get more priority, other themes may end up being done as well (no promises!).
Here's the vote link: https://strawpoll.com/e191xpa2y
