Is there somewhere we can go to voice our opinions about this decision?  I'm hoping so many people will be frustrated by this that they'll change course.

My biggest complaint is the web version, as far as I can tell, lacks the ability to flip back and forth between several open windows at one time.  This is a key feature the app provides, similar to what your views would be in the Desktop version.  I am aware that you can click on reports and open them in a new window but I need this feature in almost everything I'm doing, not just while looking at reports.

Will there be a better method for this moving forward if you're dropping the app?
