Would it be possible to add an option to use the unarmored models, even while wearing armor?
Yes, I think I could add a per-player setting allowing to turn off the armor in the character previews.
Also, unrelated question, why does character scale setting's tooltip say 25 is normal when the default is 100 because it's a percentage?
Minimum size used to be 10%, but I've changed that to 25% in version 1.1.20. Unfortunately, I've messed up when editing the English locale file and changed the 100% instead of the 10%. Thanks for finding this! I've already corrected the setting description for the next version.
