Charlie, actually customization is probably the easiest update PG can make. Function wise it is packed. The beauty of customization is that each user can adjust the program to their liking. Customization is like: You do not place the bed in the kitchen, just because you can sleep on it...But perhaps some would like that...to be close to refrigerator at night
(Extra tracks would be nice though, and a few other relatively minor things)
As far as my opinion on Realband "merging".(I knew I am going to be eaten for breakfast) I think this was misunderstood. Here is a simplified version of what I was talking about. Take a look at the picture below. You open "one" program, with option which program you want to start by default. So lets say you work in BIAB and you need to edit some stuff in Realband, you click on magical button on the top and your BIAB project is transferred to Realband freezing the project in BIAB without closing it, until you click "BIAB" button in Realband. So basically you have ONE project that is editable by ONE program that has both BIAB & Realband at the same time. I know there are many things that are involved, by I do not believe this is such a horrible idea.
