You always wanted to see your church.tools hierachy visually? Just give it a try: https://ctorganigram.joameyer.de I recommend using id / token login, as this works flawless - also with 2FA enabled - but email / password login is supported as well.
Just install the files on a webserver supporting php and login.
You can customize the two variables $group_leader_role_names and $group_members_role_names to better fit your installation's role names.
