Screenshots of the Hipihi interface with English annotations should be available very soon. Zafka of Hipihi showed them to me for proofreading. This will be a great boon to non-Chinese speakers. Expect them in the next or two, I believe.
From this I learned that Hipihi’s prim editor lets you select multiple prims and align them by x,y,z, or all axes. This is a feature that has been asked for many times for the SL object editor but never implemented. Hipihi also lets you select multiple prims and do non-proportional scaling with the mouse. This will be nice for builders.
