1. Inability to switch branches in the editor [0]
2. Full project search "to be enabled at a later date"
So I can't switch branches off of the default branch and I can't search the entire project. To me, this undermines your claim that the new web IDE "will provide users access to more features" and in fact I don't find it useful for hardly anything in its current state.
I get that it's a beta, but it seems a very incomplete one, at best.
