Ok, I have pushed out the last of these little changes, but it won’t be obvious just yet.
You can now change your trade waiting period between the default 48 hours and 24 hours. This will show up in the Commissioner Tools / League Settings page when trading is not allowed, so after the keeper deadline and before the draft and after the trade deadline and before the end of arbitration.
I know this was a very popular Wishlist item, so hopefully more than a few leagues take advantage of it!
