 .
    The dialogue box that appears (see figure 1) provides quite a few
    customizable options. One can have up to 4 groups and each group can have as
    many texts as you want. Of course, the more texts you add, the more
    differences that will be highlighted in each, so the results are most clear
    when you only use 2 texts. Also note that the order in which the versions
    are listed determines which is the base version for the comparison. Colors
    can be customized, and groups of results can be toggled on/off separately.
    There are two methods of comparison though the LCS (Least Common Substring)
    will be used most often. There are other options for ignoring accents and
    moveable-nu. When comparing more than 2 versions at a time, the
    "Cross-compare all versions" provides a better display.
    Additionally, note that each group has an "Export" option. By
    clicking that button, BW8 will compare the versions listed and export a list
    of every verse that has a difference and send the results to the Search
    Window. It took about 15 seconds to generate the list for the whole NT. (For
    more info about the options, remember simply to hit the F1 button when in
    the dialogue box.)

Usually BW8 displays text verse by verse, but one can also specify a passage of any length. In order to see texts in vertical rather than horizontal parallel, one should use the Parallel Versions Window available through the menu via Tools > Viewing the text > Parallel Versions Window or by clicking on the panes button in the toolbar. (See figure 2.) This window is also customizable, but the best feature is that also allows for the kind of setup shown in figure 2 where I have compared 4 Greek texts, placed the KJV (which used the Textus Receptus) and ASV (which was largely based on the Westcott & Hort text) on either side, and enabled comparisons of both the Greek texts and the KJV/ASV texts. It is somewhat difficult to save text results in BW8. The Browse Window results may be copied/pasted into another program (be sure to enable "Export Colors" in the text copy configuration dialogue), but can not be saved at all in the Parallel Windows except by snapping a screen image.
