The quality of the topics varies a bit - it seems newer APIs are documented in greater depth whereas older APIs are sometimes not really documented at all. I understand that the methods of the Core object are seldomly used, however having a sample for all “central” methods and classes would really be helpful.
We’ve put considerable effort into improving the help quality in LL21, adding new samples, chapters on web reporting, documenting all relevant web classes etc. However, this is an ongoing effort, so I’ll leave this suggestion open for voting anyway.
