The first official build of WebPositive for Haiku is now out. Tthe primary developer, stippi:

I’ve been working fulltime on WebPositive, often from ninish in the morning to about midnight, with some pauses in between of course. Except for missing bookmark support and an almost useless browsing history menu (because seemingly unsorted), WebPositive has become quite usable[.]

I concur, even without bookmark support, cacheing, and a number of other features, it’s faster and friendlier than BeZilla.
