[WP-Syntax] : new functionnality -> expand or hide the block

hello

i’m looking for a plugin who add to WP-Syntax the possibility to expand and to shorten the block code.

i have a lot of code (AS/PHP/…) who go beyond a good visibility.
when you have more than 50/100 lines, it’s not very good to have all this code mix with the normal text.

thank’s
