Watching the playback of the live stream, one thing occurred to me.
There are 3 trait trees, light, medium and heavy.
There are many cosmetic options which change this like barding.
You have the option to save multiple configurations.
Is it possible to assign different cosmetics to your different configurations, so for example my heavy setup gives my horse a much more heavily armoured appearance and vice versa? Or are there other visual references to which trait line your using, such as heavy horse being bigger?
