Describe the feature

While trying to get a theme similar to lapce's tokyo-night-oled going, I found myself repeatedly wishing there was a tool that lets me click any element in the UI of various views in Zed and lists all theme keys that affect it. Even with tooltips from the schema it's often not obvious what a given key does and the list of possible options is very long, making searching for the right one a very tedious endeavour.

This could of course be extended to a full-blown theme editor GUI that lets you export the full theme and test things like switching between dark and light variants on the fly.
