Another great option is to make a "narrowing" filter -- I.e, when you
start typing characters in the filter entry box, the list dynamically
shrinks to the *subset* containing this sub-string (think awesome-bar
in Firefox or the search boxes in kmail/kaddressbook).

Although regex are more powerful, the "narrowing" filter pros:
 * Very simple and intuitive for newbies.
 * No need for extra controls (Apply button, etc.)
   as the action is immediate as you type.
 * Add/remove/change filtering are all the same
   action (type/edit the string).
 * It's important to narrow by sub-string (not prefix), so it won't
   be very limited.
 * Making the matched sub-string bold in the list (as in FF awesome-bar)
   would make it even more intuitive.

However, if this is going to be implemented, it's important to have
it for any list which may be long (for consistent look and feel).
