[Greasemonkey] changing framesizes

[Andre]

Happy New Year :-))

I am using GM on a site that is using framesets. One of the frames is a 
bit tight with my added buttons. Is there a way to change that with GM? 
I want to resize the innermost <frameset cols="116,680" ...

Abbreviated definition:

<frameset cols="*,796,*">
   <frame name="links"/>
   <frameset rows="58,*">
     <frame name="oben"/>
     <frameset cols="116,680" >
       <frame name="persoenliches"/>
       <frame name="mitte"/>
     </frameset>
   </frameset>
</frameset>

Cheers, Andre
