We have a couple issues with Safari. One of them is related to the layout because Safari 7 has some issues with flexbox but it's already fixed in a branch and should be merged really soon. We also have an issue with this JS problem with Safari when creating a new project that we are reviewing. Thanks for your feedback. Everything should be working well with Firefox and Chrome if you want to create a project right now. :)
