Maybe this is a good time to tell you about this week's changes:
-all changes are linked to the previous and next one. When you click a
change the pop up has 'back' and 'forward' buttons.
-there is a 'go to first change' and 'go to last change' icon in the
header above the content diff.
-i added shortcuts to walk through all changes. for instance when you
want to go to the first change on a page you can press [left arrow]
right after the page loads. After that you can use the arrow keys to go
back and forth quickly.
-the selected change is highlighted in orange for 2 seconds
-the explanations for the curly underlined changes are now in a somewhat
human readable form.

I believe these changes by and large solve the usability problems.
Unless of course I'm overlooking a certain use case.

I also would like the diff page to be more prominent and easily
accessible. I'm not sure how the people at outerthought feel about this.
In the end Daisy is not a html diffing tool.
