Considering the excellent work the goes into areas such as themes and CSS I can't believe that we're still stuck with these graphics !!
Personally I'd like to see several "sets" of professional looking icons. Hell, I'd do it myself but I'm no graphic artist.
This would be a way to very clearly fork away from the visuals of Post-Nukes scary past and head off down a different, brighter, more wholesome path toward a greater future !!
Sorry, am I getting carried away ?
BTW, congrats, PN is 7th most active at SourceForge (a new PN record). My own humble project over there is in 3,216th place (and I've been putting a fair amount of time in !!).
