Planning for JavaFX.next

Hi folks, Development on JDK 9 is slowly starting to ramp down, and we are starting to turn our attention to the goals for JavaFX in JDK 10 and beyond. We are starting to compile our list of what we think is important, but we really want to hear from the community about what their highest priorities are to them. As always, it's important to keep in mind what JavaFX is (e.g. it isn't aiming to be a high-performance game engine), but even still there are bound to be a number of places where people might want to weigh in, for example: * New layout containers (e.g. Flexbox) * Public APIs for UI control behaviors * Marlin renderer enabled by default * Support for CSS animations * CSS performance improvements * TableView improvements (cell spanning, row / column freezing, etc) * TableView performance * Focus traversal API * WebGL support in WebView * Improved image I/O support * A JavaFX equivalent of the AWT Desktop APIs * Multi-res image API * NIO-backed writable images If there are other areas of interest that aren't listed here, please start discussing them and we can work together to determine priorities. If all you want to do is add a +1 for one of more of the items above, even that will be very useful. Thanks, -- Jonathan
