It is not clear. It may be if I was viewing the thing on a 30" monitor but the black UI style is unreadable to my old eyes.
Now that I have seen the setting, I must say it is very cumbersome. There needs to be a way to change all the gutters at once and not change the text box size. Or the gutter setting should be an integral part of the initial setup like Quark and Indesign
I hope you don't taker offense at my criticism, just that it is very exciting to be a beta tester on another layout program. I bettad InDesign 2, Quark 5 and some other stuff. Good job so far but you have along way to go.
