for now i have to disable the tabnumber code, as it breaks *completions* in muttator. Sick, yes, but that's due to:

No chrome package registered for chrome://browser/locale/tabbrowser.dtd
Error: undefined entity
Source File: file:///home/maxauthority/code/muttator/src/content/bindings.xml
Line: 23, Column: 9
Source Code:
        <content chromedir="&locale.dir;"

It might make sense to rip the vimperator only css into a skin/vimperator.css if possible, but not at 3 a.m.
