RowList -Dynamically Updating

An interesting dilemma.  The way scenegraph works is it redraws everything within the current update group.  It appears to use a back buffer and front buffer just like roScreen did and when it swaps the buffers it causes the flicker.  You can minimize the problem by breaking each row into separate components but that makes it more complicated to manage.  The end result is - the less area it needs to redraw the less pronounced the process will be.  What you could do is append an item to the end of each row of content for 'More' - and then when the user selects that load another 50 items and replace the row content.  That would make the change to the first item in the current list make sense - and perhaps prepend a "Previous" menu option before the beginning of the new content.
