I thought Pro was only for AI features as well (that's what it said when I installed Raycast), but this dialog is saying Pro is required for custom window layouts as well. I only discovered this today when I was trying to create a new command to paste the screenshot from my clipboard into Preview for OCR.

I wrote my own window management with Hammerspoon, mostly duplicating what Rectangle et al do, but with specific tweaks just for me.

The most useful feature is the fact it uses my display layout + wifi name to figure out where I am and adjusts window locations accordingly.
