# - Mocha-automate the main page's form so clicking on rev links in the table
|
|
# change the default filename and revisions.
|
|
# - Add a tab width input to the main page's form.
|
|
# - Include log message in wasted horizontal real-estate of Shortcuts frame.
|
|
# - Make old and new diff lines go to separate, side-by-side frames, and use
