Thank you for your input! I'm glad you liked it. I always hated close followers and even had a stagger-follow plugin in the past, but it was never enough.
1: I'm not sure I understand this question. They can wander around, and even face different directions. Do you mean not have them look around, and just wander in one direction and stay facing that way?
2: I could look into that soon.
3: I have a plugin for that now! It can be found here. I can gift it to you since oyu bought this one. I should include a bundle deal for these two plugins, tbh.
