OOo should not be "just" M$Office -- this sould be better in the same manner
that Linux is better. 

I sugges to supply user with more advanced functions for text processing. For
example function: 

Sed(<input>, <program>)

which takes input text and applies to it given program. For example

=Sed("alfa beta gamma"; "s/[ae]/[AE]/g")

will put "AlfA bEtA gAmmA" in cell. 

Why do I need so sofisticated text operations --- see attachment. 
I have text files which contain product name and quantities. I have
to cut each string into separate parts and then convert strings
to numbers. This is simple and can be done. But I have had some 
tasks to do where texts were not aligned very well - I have had 
to use sed, while this should be done in Office without scripting.
