I'm liking it so far. The flat UI, the paper-kifu feeling, the way of showing game information. If I were to be picky, I'd ask for exactly the same app, the same neat design... and editing capabilities, so I can comment my own games with it. Letters, triangles, all the goodies

Also, click-selecting variations, probably adding a preview of variations, too (to browse Kogo's Joseki Dictionary, for example, by tapping a, b, c etc) would make it awesome. Although currently it works very well with Kogo's (takes a little to load but opens perfectly fine and browses as well)
I'm also missing "Open in..." so I can open SGF files from email straight to Qipan (have to download to dropbox and then to Qipan now.)
But for a version 1.0, I'm very impressed
