Max & Tim, thanks for building this. This is something I recently spent 2 weeks trying to solve, then more pressing issues came up so we threw more CPUs at the problem. So from that I can appreciate how complex this is to solve, and the UX is awesome, so cool that you can edit the cache keys in the UI.
Do you/will you handle caching individual request layers? For example if I need part of my query to always be fresh, but some expensive part can be cached for hours, is this possible? And somewhat related, what about keying on operation variables?
