Should we merge scripts and scenes into the same section as they serve the same purpose.

I've never used scripts, so I don't really know. Automations feel different since they are rarely turned on and off, at least in my system.

Scripts and Scenes seem pretty different to me but I barely use them both so 🤷‍♂️
