While it make not be a big deal for one item, I've worked on many projects that deviated from the standard CRUD style and it was okay at first until it became too much. One or two additional actions may not be a big deal, but after that it starts to become a mess. Personally, I'd rather namespace the items and keep the controllers smaller.

Ah, really cool. TIL about inputmode.

The issue with devise and broadcasting is warden gets angry. To get around this, I will pass a user object into the partial or use the Current Attributes. You have to be careful with broadcasts and the current user object because all broadcasts will be in the context of that current user. As a workaround, I have broadcasted an empty turbo frame tag with a src attribute which makes a request back to the app to get the actual current user object but depending on your scenario, it would create  a n+1 request situation.

My next episode is on hotkeys and like your idea! I'll implement this.
