Awkward on iPhone

The word list and definition areas are locked in at awkward ratios on my iPhone. More room is needed for the definition area, and it would be best if it could be sized by the user. Otherwise... works. Has a long way to go. Would be nice it if allowed one to peruse (full definitions, not just lists), especially if by discipline (strat, sed, paleo, igneous, mineralogy, etc.).
