--ignore-whitespace sounds like a great feature, we have some files that have had EOL conversions so we have to jump through hoops to annotate them (e.g. using a revision range that ends before the whitespace change). Has it been implemented yet? I tried it with bzr 2.3.1 and got "bzr: ERROR: no such option: --ignore-whitespace", and it's also not mentioned on http://doc.bazaar.canonical.com/latest/en/user-reference/annotate-help.html
