Japanese v3.1 (available late February) is a major update bringing the detail of a kanji dictionary into each sticky:

Kanji database
◆ Contains all 6355 for kanji kentei level 1.
◆ Detailed radical information.
◆ Kanji are broken down into their elements.
◆ SKIP codes.
◆ Stroke count.
◆ Dictionary codes.
◆ Radicals, elements, stroke count and SKIP codes are hyperlinked to allow you to drill down to related kanji.

New English -> Japanese dictionary
◆ Live searching as you type.
◆ Entries grouped by English keywords.
◆ SKIP searching - just type the number (eg, 2-5-10).

Other
◆ New deck list instead of the spinny wheel thingy.
◆ Saving a sticky now uses a deck called 'Saved' not the current deck.
◆ New iPad font.
◆ Bugs fixes.
