I actually really like the checkbox on the right hand side. I don't need to see the checkmark. If it's checked the strike-through tells me that. If it has some status then I see that in the color, which draws the eye, and the light line keeps me in each task if I move back and forth.
I really dislike how much focus that checkbox gets in most UIs. Why does something you will only use once get so much attention? I like how OF2 has enlarged it and used color to make it actually useful instead of just sitting there taking up space, waiting to be used. I already know my tasks are sitting there, staring at me, waiting to be finished, judging me.
It might be that light line (reminds me of the old trinitron wire sometimes, in how faint it is) that really needs improvement?
Also the Note, context, status line thing looks too much like a bullet, but I'll post about that elsewhere.
I use OF2 full-screen, 27" iMac + TB display, and the lack of clutter (one persons wasted space?) really helps me do, instead of fret about how much there is to do... remember the judging? I have a love/hate relationship with my task list.
I have OmniPlan if I want clutter, and more judging ;)
