Aw, bummer. Is Brow 2 still being worked on? I'd totally upgrade just for that one feature.
In the early times (first trimester 2013 year) it was really on going, there was even a team testing it, however, months later Borf stopped it due to personal reasons.
He totally has great ideas for it, and I'm sure he will make them one day, but its hard to tell when. Btw It was just days before that I talked to him regarding it, and seems he was a little interested again, so maybe we'll have some luck soon.
