--- Comment #14 from Wolfgang Jäger <jag at psilosoph.de> ---
Once again this was mixed up with the (re-)unification enhancement bug #87274. 

Unification should be expected to be much more difficult than avoiding
fragmentation! 

This is not about an enhancement, but about a REGRESSION!

To draw the fragmentation discussion back to this topic where it should
continue, I include the recent post I made there also in this comment:

Quoting myself from bug #87274, comment #14:
""
Now I am talking only of the fragmentaion, not of the (re-) unification which
would mostly not be needed if not first fragmentation took place.

The problem arose, as far as I can tell, at (about?) the same time as the CF
manager was introduced. In advance it was not just "not visible". It was not
existing at all - and it still does not exist in AOO up to V 4.3.1. (where the
classical CF dialog allowing for 3 conditions is still used). 

To be clear about steps to get evidence for my claim: 
Create a spreadsheet document with freshly defined CF (more than one probably).
Save it.
Open it in AOO.
Copy/Paste around in a way you know would cause unnecessary fragmentation in
LibO.
Save again.
Open in LibO.
Call the CF manager.
Verify: No unnecessary fragmentation.

Some developer should study the CF-"code before CF manager" and find in what
way fragmentation was NEWLY introduced. Repair should be feasible then. 

Unification of "equal" CFs (how to define exactly?) can wait then.
