Flagging important or favourite posts

I just realised that I have a need to flag certain posts 
that are more important than others so they don't get lost 
in the sea. I can't just create an "Important" category, 
because I have posts that already belong to many different 
categories that all need to be marked as important.

It occurred to me that the tags plugin could be used for 
this (just have an "important" tag). Is there any other way 
to do it?
