An enhanced Ext.List which should be able to handle large(ish) lists (1000+
items) by limiting the number of rendered items using a sliding-window
approach.
Based on 'BufList PR3 - pre release' by MahlerFreak, posted here.
NB: Sencha Touch 2.1.0 beta 3 introduces a rewritten Ext.List component which can also handle large lists natively.
Release notes here.
