I was experimenting with hook_menu in a theme. It doesn't seem to work.
I found this page listing theme functions. It is safe to say that if hook_menu is not listed here, it's not available to themes?
Is this a safe guide to what themes can do with code or is it more complicated than this?
I was interested in creating a second page of configuration options for Tatsu theme, to resolve this issue: https://github.com/backdrop-contrib/tatsu/issues/72
Is it possible to create a second page or second tab of settings for a theme?
