The logs are in the wrong place
Actually, the logs are stored in $XDG_CONFIG_HOME (or
~/.config/poezio/logs/ if not set).
Although this is slightly better than having a /.poezio,\ this\ is\ still\ not\ xdg\ compliant\ ;\ the\ user-data\ not\ related\ to\ the\ configuration\ should\ be\ stored\ in\ $XDG_DATA_HOME\ (or/.local/share/ if not set).
I also think that allowing a custom folder for the logs in the config file could be a good idea (like log_dir = …).
