New Plugins Query Model

[taooceros]

We can let plugins return a IEnumerable instead of a List (IAsyncEnumerable for Task<List>), which basically natively open the potential of some early result and some later results without invoking results again and again, but providing with what's new.
Further, I would like to investigate the potential of letting the listview to sort by itself so we won't need to readding to observable collection every time.

Sounds promising 👍
