The

IDataListSource.GetItems

method isn't changing to async yet. The caller of that method isn't async and working it way back up the chain isn't async either, so if I made it async, it'd just be faking it (at this point in time). BUT! I must admit, I still don't fully understand when things should be async or not these days, (apart from the typical blanket statement of "ASYNC ALL THE THINGS"! 😅 With the upcoming DataPicker editor, that's different, as the items will be loaded in through their own API controller endpoint, so can be made to be async. So for Contentment v4.5, there'll be a new interface for that editor to do the

GetItems

as async - but only for DataPicker, not DataList. (if any of that makes sense? 😅 )
