Great!

Just in case: A few words about using the new kformula lib.
(I always wanted to say this. :] )

- You need one instance of KFormulaDocument inside your apps document. It can 
contain any number of formulae.

- The actual formulae are instances of KFormulaContainer. Ask 
KFormulaDocument::createFormula if you want to have one.

- Any formula is able to read an old formula string. See 
KFormulaContainer::importOldText. But please note that this method might only 
be called while loading. It doesn't change the undo stack. So you better make 
sure it is empty.

- If you want to edit a formula you need an instance of KFormulaView or 
KFormulaWidget (which in turn uses KFormulaView). KFormulaView is the view 
and KFormulaContainer the document.

- There are bugs.

I suspect the kformula lib will need adaptation if it is to be used by new 
apps. Right now there's only kword, the kformula part and a small test app 
that use it.
