So, fuck, there has been a Intel build of Ecto out for nearly a month. This is, of course, unofficial and unsupported and probably cursed by a mummy or something but it is much, much zippier. Opening a preview pane or refreshing it seems much faster now. I will say absolutely nothing about stability because opening my mouth about any issue even peripheral to that of stability is a little like seeking shelter from a downpour of anvils beneath an electromagnetic umbrella. It is fast. I'll put that out there without having my hand bitten off.
