Can anyone who's moved from Vimperator to Pentadactyl comment on how hard it is to port your .vimperatorrc to a corresponding .pentadactylrc? I've got a bunch of bookmarklets set up in my .vimperatorrc with custom shortcuts (Readability, QR code generator, add to InstaPaper, etc.), plus a lot of custom shortcuts.
One of the big things I like about Vimium is that it allows for lettered hinting, which I prefer to numbered hinting (which is the only option in Vimperator). Also, very annoyingly, you can't use "[" or "]" as shortcuts in Vimperator - I'd like to use them to switch tabs to the left & right, but I'm stuck using "{" and "}" instead. This is just a bug, but the low activity level in Vimperator means there's no one around to fix it.
Actually, any key that you don't use as a hintkey can still be used to narrow down the hints. I use lowercase hint keys, and I can hold shift and type the link text (as the matching is case-insensitive, but the labels are not). It works very well.
For aesthetic reasons I like to render the hint labels in uppercase. It can be done by adding text-transform: uppercase; to the Hint selector with :highlight
