At least in this version on my machine(s) and IMHO, Scrivener has nothing to worry about. A tutorial would perhaps help but I couldn't get rid of the start page and enter into a document in the middle window ... nothing seemed to work.

Page Four was a decent though very limited alternative to Scrivener. This? Not so much. On top of that, I've a 770K i7 cpu, SSD PC and this thing is s...l...u...g...g...i...s...h...ly slow

Not interested. At all.
