Because we tell the plugin to cache forever, live-dynamic content must be served over AJAX or similar mechanism.
pros
- site speed shouldn't degrade due to content-sections
cons
- may lead to user surprise for site-admins (each time the CPT is saved it regenerates it's transient)
Perhaps add a filter so the ttl on transients can be modified by meta value? Even 1 second transient could save a lot of processing for complex content-sections.
