Crosswalk has only been around a couple of months, and in that time it's already improved a lot and fixed a bunch of bugs....
Crosswalk sounds pretty good, i tested it a bit, but it needs more work, still, lots of promise there, if you guys work together, it will be what exactly we need at moment, doesn't matter if is native or non native or whatever, as long as we know is official supported by you and its not limited, its good.
iOS CooconJS does seem to work better than Android in my case, so its ok, you are limited by memory, their ads network and so on, but its doable.
Optimizations sounds good, beside a few quirks which i still dont understand on performance, i usually get a good performance lately but they are still bits that make no sense, of course i ve been fighting with mobile web html 5, which is a mess for active games, but oh well, lets hope the tech improves.
Also we need a better forum structure on support, now is just a mess tbh. I recommend a few sticky topics which will help a lot in How do i?
a) Best practices for html 5 web development (performance and proper coding structure)
b) same but for mobile
c) same but for mobile web html 5 (this is one is a pain) here are some looses in performance sometimes that make no sense. Of course its mostly related to young browser and canvas2d, but sometimes i feel lost and there very few answers on the forum, beside the common sense tips. Example: Canvas manipulation on Safari doesnt work well (or maybe i am doing it wrong), no full screen trigger on Safari, tips on how to fill the browser screen, stuff like that. Performance tips and so on.
C2 is easy to use and intuitive for the most, which is the reason we all use it, but to keep a decent performance on some platforms, we need more info, topics, stickies, etc. Of course most of this comes with experience and time, but sometimes its annoying:) For example in my last mobile web html 5 experiment i had so much shutter by just moving 3-4 objects on screen, for no reasons that i found (no ticks events, no endless loops, no crazy collision checks, etc). Of course on point rendering things were better, but Safari doesn't even know that.
The new distribution and publishing subforum its a good idea.
