I really love the "hide pinyin" feature that Skritter has; actually I feel like it is necessary to study effectively. I would really like it if an option became available to hide the pinyin of a word during tone practice. That way the tone of the character would become associated with the character itself, not just the pinyin for that word.
I often find myself immediately looking at a word's pinyin to remember the tone, and not the character itself.
Anyone else think this would be a good idea? I feel like it might not be too hard to implement because the "hide pinyin" feature has already been developed.
