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.
