Let’s imagine I am going through many records in the services model and in each there is an “SEO” fieldset. Normally this fieldset is collapsed by default as you don’t often need to make edits there. But today that is exactly where I am going through and making many edits across all records.
Proposal
Default state of expand/collapse is applied once per session only. As you navigate between the records of a single model, the expand/collapse state of fieldsets persists. The default states would be reasserted during your next session.
