" It's a BIG problem in open-source : every modification can be done. but some modifications causes my version to be no more upgrabale with the "standard" one, so any evolutions in the "standard" version must be checked and corrected to fit my own modifications. That's why I think we must have only 1 version, even if it causes some dis-agreements (not sure of this word in  english ?)
In the long time, it REALLY BETTER. " 
    
 
I concur with Paul -- and I note that a good number of the items earlier (barcode sizes, etc) can actually be handled through modularization, etc.  -- allowing us to maintain the "one version" of koha, while allowing the flexibility people seem to want.
This is one of the things the emails I intend to get out to you all individually will address, at least in part.
