Product suggestion.. Within Metrics and Data - Data Sources I think it would help to move 'Dimension Columns' from the advanced options of 'Edit Query' and in to 'Configure Dimensions' I had an issue with my dimensions so spent a while poking around the 'Configure Dimensions' section, and indeed the 'Edit Query' section, but would never have thought that dimensions lived within the 'advanced' section of 'edit query', given there's a whole modal about 'Configure Dimensions'. The 'advanced' section isn't mentioned in this documentation either. Evidently I resolved it, so its not a big issue, but thought I'd mention. Hope that makes sense/helps.

Hey Joe! Agreed here. It's a bit confusing! Let me open an issue and hopefully we can resolve it quickly.

Added to GitHub here- https://github.com/growthbook/growthbook/issues/3015 Also, submitted a docs update request to document the advanced options 🙏
