You know of course that you have the power to implement everything you want locally don't you? :-)
But another guy in my group will collaborate with me on this document and it would be easier for him if it is in lyx.1.5.0.
Will this feature involves a format change? If yes, how much time do you need in order to implement the very minimal change to support it?
I have done more than minimal for this feature. I can polish and submit a patch for review later today. I need some help on lyx2lyx though. Cheers, Bo
