two ideas i happened to stumble upon while
dev-nulling my stuff in my room.
(if that doesn't make sense to you, i know how you feel)

Line numbering (two options)

• Option in user settings that'll display line numbers before each line of code
• option to specify with a <code> tag, i.e: <code ln="on">

syntax highlighting
option in user settings that'll turn on or off syntax highlighting.
not for me, but for people *really* new to Perl.
would spoil the fun of obfuscated code though ;-)
