this gets brought up from time to time and I agree with the OP! BIAB is absolutely amazing in what I can achieve but has such an outdated interface. I find it to be,

1) cumbersome to use because it has not kept up with user interface guidelines (which are not just "eye candy" and are proven to improve user satisfaction when properly implemented)

2) overly complex which makes it hard to remember how to do things and wastes time as I click here and there and finally come to the forum to ask "How do I..."

3) inefficient to an organized workflow because sometimes I need to search menus and sometimes I need to click buttons and sometimes the solution is buried on a dialog window.

4) not as much fun to use as some of the slick looking modern software like the newer DAWs

If I were in charge of PG Music I would make a complete GUI redesign my highest priority. I would bring in qualified consultants to review the program and outside GUI programmers to implement (or at least advise) the new GUI. I would integrate all of the latest bells and whistles from the native OS's and I would make a scaled down mobile version for iOS and Android.

Then I would market the crap outta this amazing product and feature the slick new GUI in every ad in every industry mag, every music store, every music school, etc. This product is so amazing already that if it had an equally amazing interface it could be 100 times more popular and successful! I have friends who are so thrilled with GarageBand but BIAB blows that program away! EXCEPT for the GUI!

And to those who say GUI is unimportant, I'd say you are simply wrong! People spend big bucks on stories. They walk past the free water fountain to spend $4.00 on a bottle of fancy water with a lovely package and a story of artisan wells! They ignore the cheap but delicious cup of joe at their local convenience store (or their house) and instead pony up $6.00 for a cup of magic at Starbucks.

Maybe it is flaky and lame but people care (deeply) about such things. If PG Music decided to own this market for the foreseeable future they already have the product with which to do it but they need a pretty face and a great story!
