Re: LilyPond Enhancement Proposal (with Bounty)

[Abraham Lee]

Paul,

This sounds intriguing! First of all, my best wishes to you and your startup 
company. May you have great success!

Secondly, I'm not entirely sure I understand what you are trying to avoid with 
the text above measure bars. Can you give us an example or two showing us 
exactly what you mean? I think that will help us know who can help you. 

Regards,
Abraham
