Hi Flynn,
I posted a few months ago about this.
With Atahualpa, I wonder if it is possible to put a slight delay on menus collapsing when you go off them. (maybe a half second). I know this is probably difficult but it really helps if you move diagonally with the mouse down into a sub menu - so that you don't lose it all.
Suckerfish were maybe working on this.
I would like to propose that I will give £15 towards the development of this if enough other people were interested in also paying a similar amount to make it worthwhile. Maybe you could decide what would make it pay enough. If it looks like a go-er I shall pay first and then we trust everyone else will stump up (pay).
best wishes
Heimir
