     9 Features to add:

    10 * make the left and right parts of the viewer independently scrollable

    11 * make the test list filterable

    12 ** default to only showing unexpecteds

    13 * add other ways to highlight differences other than circling?

    14 * add zoom/pan to images

    15 * Add ability to load log via XMLHttpRequest (also triggered via URL param)

    16 * color the test list based on pass/fail and expected/unexpected/random/skip

    17 * ability to load multiple logs ?

    18 ** rename them by clicking on the name and editing

    19 ** turn the test list into a collapsing tree view

    20 ** move log loading into popup from viewer UI

    22 -->
