Being a newcomer to WeeChat, I reacted sort of badly to its default theme.
It looks like Irssi's default theme, except it's been added a lot of unnecessary bells and whistles. A lot of pipe characters, square brackets, ASCII art, fancy colors, making it look like some teen gamer's Matrix fantasy rather than a simple, efficient, well-designed tool of communication.

Would someone perhaps, like to join me in creaeting the absolute simplest theme possible? Something like ircII from back in the day. Something that doesn't scream for our attention, but rather goes by unnoticed so we can focus actually communicating with others.
