    The abilities to open games "as problem" (for guess-the-next-move) or "as book" (for playing out on a real board) are absolutely brilliant. I won't use any other sgf viewer for reviewing pro games. And the game list with previews; also brilliant. I only wish I could open games as problem/book when I open them from a file viewer instead of relying solely on the in-app file browser to do that.

    The editor is great for browsing through sgf files. Going through variations works nicely .
