+1 for CSS perf (diagnostic tooling for slow selectors like @Daniel Gloeckner 
referenced earlier would also be a bonus)
+ for scene graph rendering perf
+ table perf
+ table features and fixes (column freezing, row span, selection model fixes 
and memory leak fixes)
+ integration of controlsfx into JFX.
