How about a WinXP IE look (Luna) for the next release?

What are you referring to here exactly: a new skin for K-Meleon, or a manifest file to support the built-in XML Windows XP skins?
Being a user of Windows XP, I've noticed a few program authors are including a manifest file for the Win XP skins, however I don't believe that this should be any priority for K-Meleon and it's authors. I mean, after all it's just eye-candy rather than actual functionality that I'm referring to here.

I use kmeleon in Big5 locale (zh-TW). I found out res and component(lang file) to us-ascii
(en-US) , I want to look html not head with
<meta http-equiv="Content-Type" content="text/html; charset=big5">
<meta http-equiv="Content-Language" content="zh-tw">
,so I can read chinese in simple html too, is it possible to change default locale
without change source code ?

my 2 cents worth - spare me the candy-ass XP look ;-)
