Thanks for the suggestions! FMA is definitely something we want to add. The question is what to do when hardware doesn't have FMA, as it's quite expensive to compute manually. Some applications would want to fall back to discrete multiply and add, but of course that rounds differently and other applications don't want implicit rounding differences between platforms. I believe the solution is to give applications a say in what happens, though the details are still being discussed. The load-and-deinterleave/store-and-interleave operations are good ideas too. They're a little more complex than we could accommodate the initial version of SIMD.js, but they're definitely things we should consider. Working with 8-bit and 16-bit data is an area where the current version of SIMD.js is fairly limited overall. Extending loads are a good idea, and in general I'm hoping a future version of SIMD.js will provide a much more complete set of operations. I'm interested in any other ideas you have as well. SIMD.js is being developed at https://github.com/tc39/ecmascript_simd https://github.com/tc39/ecmascript_simd and you're welcome to file issues to send us your ideas. Thanks!
