When, oh when, Adobe, will we be able to use blend modes inside symbols? It seems so silly to be able to do everything, EXCEPT the most basic and common of operations. Especially multiply is used so much when making mockups of existing pages and moving cut out pieces around.
I don't see any reason - on a technical or usability level - that would justify this limitation.
And while you're at it, why not make groups behave like symbols (ie. like in Flash) or show their contents in the layers panel (ie. like in Illustrator). Or why not be really nice and do both!!
These 2 limitations are the only things that really annoy me about Fireworks on a daily basis - the kind where you shake your head and think "this is so basic, it should've been there for last 5 versions".
Will you ever fix these things?
