Hi Andreas,
another big issue is the x64 Browser requirement. Normal people do not use Firefox Nightly x64, so nobody could ever use it (except devs), even if you have a perfect build =(
HTML5 would really be an epic thing to have, especially for the architecture biz! But at the moment it is far from production ready. Very sad…
When I look at the roadmap, October/November says “HTML5 workflow improvements” - but I think x86 Browser support is the real issue and making it available in the binary install. Should both definitely be in the roadmap too I think - or is it not possible any time soon Epic? If not we should know.
