Create a Browser with the navbar integrated
If you can create a Chrome based browser with the navbar function integrated into it, that would probably fix the issues we have with comics that have framekillers programmed into their site.
It would be similar to navigation with the bookmarklets, but with the information included in the navbar.
This may be able to be done with a browser addon instead.

What would be the advantage over using bookmarklets? It seems like a lot of job. There is not even an API for making a toolbar in Google Chrome: http://stackoverflow.com/questions/6681697/how-to-make-a-toolbar-in-google-chrome
Is this just for circumventing the framekillers? That is possible to fix in easier ways most of the time.
