I really think that you have missed the point of this list.

This list is for either developers (those who have downloaded the free code and 
work on it) or others who want to move things forward concretely.

Perfectly fine to contribute ideas, but if you are not a coder or do not have 
the time or inclination to work on things yourself, you have to be *really* 
convincing.

We continually get bombarded with ideas, wish list items, etc so we are not 
lacking in work to do.

If you cannot explain the use case, you will not get any buy in...

Regards,

Ric
