+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.
