Hi bnomei, thanks for all your information!

I have a question about your snippet for a static cache for a collection of pages for multiselect (exactly what my panel is slowed down by tremendously, see Slow panel due to fields with big queries)

Should the snippet above work without your boost plugin or is that required? Because I tailored it to my case (without the intendedTemplate filter), activated the cache in the kirby config but it didn’t change anything?!

Thanks for your help.
