Hey @yureckey
You are right, not all events which are happening on the board are exposed via “events” api in the SDK.
Right now we are supporting “new items” (which includes all types of creating an item, including the duplication), and “change column value”. It is documented in the SDK documentation (not in a very clear way, we will make it more clear)
We are going to add support for more events (change name, remove items, etc.) in the near future.
