At some point this morning or last night I must've accidentally hit the Set as Leader button on one of my wolves, I was very confused to find my icon was different this morning. I use mobile a lot at night and the early morning, so I must've miss-tapped while scrolling down to hit the Play button on companions.
Since this is a change that is pretty significant in user identification, I would love if this had a confirmation popup before being committed! Or better yet, I'd honestly prefer it to not be on the wolf page at all, and instead under Account Settings > Forum Appearance. I remember when I first started that was actually where I looked for it, and was a bit confused. ^^;
Maybe I am missing something, but I think being the profile picture is the only function of leaders? Since campaign is determined by party order and everything else is also by wolf selection. So imo it should just be under Account Settings, where it is much less likely to be accidentally changed and is a bit more intuitive.
