Significant Performance Improvements
(examples of these improvements are 50 times faster full node expansion in smart load mode)
New Layout Capabilities
Nested Bands

Customizable Expansion Button Location

Quick Band Visibility Customization (like the QuantumGrid)
Quick Column Visibility Customization (like the QuantumGrid)
Multiple Fixed Bands (no longer limited to one on each side of the TreeList)

Numerous other features will be introduced in the product but I will leave this to our beta announcement. On a final note - our goal is to allow for easy migration from v4 to v5, therefore, the new QuantumTreeLIst provides implicit streaming compatibility.
