There is mainly one perfect skin, the one that takes the look of its native OS look, like/example:
*in Linux with Gnome takes the theme from Gnome Theme/Appearance Preferences.
*in ms Windows from the current theme ( or could chose one from a win theme file).
So that it will get your fav. look from your setup from your OS, and if u change ur OS skinn the aMSN skinn would autoapply the new skinn aswell.
(ofcorse it need tuches, like people could make settle changes like choosing options for theme to be loaded or re applyed in aMSN)
It's for the future cos it needs a seperate plugin, but yeah this is one of the best i could come up with.
If someone wanna start someting like that up let me know, i would gladly partisipate, i know a little of some simpler codeing, some like PHP and some styleing ones too. Have lots of ideas how to use or solve some problems or just how it could work easyly.Otherways a minimalistic, but nice looking (not only boxes ) & smooth, should be the best for now
untill that, or similar to that would come to be in the existance.
