165 # BUGS
166 #
167 # Empty nicks, eg "<> message"
168 # This seems to be triggered by some themes. As of now there is no known
169 # fix other than changing themes, see
170 # https://bc-bd.org/trac/irssi/ticket/19
171 #
172 # Well, it's a feature: due to the lacking support of extendable themes
173 # from irssi it is not possible to just change some formats per window.
174 # This means that right now all windows are aligned with the same nick
175 # length, which can be somewhat annoying.
176 # If irssi supports extendable themes, I will include per-server indenting
177 # and a setting where you can specify servers you don't want to be indented
