After we implemented the computer prototype, our basic design layout stayed the same for the most part. Although, we did discuss alternatives that we ultimately discarded upon realizing that the ideas would clutter the screen or be inconsistent. For example, we discussed using a tree view to display words in the word look-up in the left side bar, but decided that tree views were mostly associated with outlining information rather than displaying information. Looking back, we realize that we should have paid more attention to and experimented more with the wording used in the interface. The problem was apparent from paper prototyping, but we had thought the problem was sufficiently addressed in computer prototyping. However, the problem surfaced again in later stages due to insufficient tests.
A newly implemented function/tab, the "Closed Sentences" tab was established after user request for a method of cleaning up sentences in the "Currently Reading" tab. We chose this particular recycle-bin format implementation as an extra function for efficiency, user-control, and error correction.
