listview wishlist

1. To be able to update an existing item properties (text, colors, bitmap etc.)
2. to know how many items are in the list (= size)
3. Add an item at (after or before..) a defined index - opposite to RemoveAt.

I know all these can be done on a simple list and then update the listview, but it would be nice to have it directly also, since the updating of the whole listview may take a long time with bitmaps.

Another useful item would be the bList equivilent of IndexFirstShown. In my app I have 275 Names/Telephone Numbers. In my B4PPC version of the app I can search for a given starting letter, or for a particular name (or part thereof). When the search is completed, the match is the first item shown at the top of the bList. I'd like to duplicate this funtionality in the android version.
