Have you looked at the ListCollectionView? Is there a reason not to use it's children, the ArrayCollection or XMLListcollections?
What other features would you be looking for in a collection framework?

I want use LinkedSet data structure, because I will use LinkedSet to store and retrieve thousand of data, and LinkedSet has the ability of check if the data is duplicate, ArrayCollection's performance is bad, LinkedSet in AS3Commons-collection framework has a good performance and meet my requirements， but it can't work in ComboBox or DataGrid(ComboBox limit the dataProvider type)

I'd be cautious about loading thousands of data elements into memory for the app. You might want to investigate a server side piece that supports some kind of data paging. I believe LiveCycle offers this. You may also consider creating a LinkedSetCollection class that extends the ListCollectionView, but uses the LinkedSet as a source. Then you can probably use it as a dataProvider to the ComboBox and DataGrid.

Your best bet is to look at code for ArrayCollection and XMLListCollection and then use the same approach. But, if you have further questions feel free to ask.

You'll have to decide that for yourself. You can easily add in the method signature with no implementation. Or you can always add items tot he end of the [or beginning] of the list, ignoring the index parameter.
