A lot of people seem to want a Solidworkesque or Fusion like transparent model browser. Solid Edge also has this. While it does provide more screen real estate, it can also be quite hard to read. So I hate to say it I like Solidworks implementation of it.
I would have it set to the current Inventor method most of the time. But having used Inventor HSM & HSMWorks, it aint half handy being able to add a transparent browser tree on the side of the HSM browser, there are a number of occasions where drilling down into components and features in the model browser would be very handy while keeping the CAM panels open. Figuring out what you need to do with holes, or checking draft angles etc..
So while I wasn't a fan, having seen how it can be leveraged during CAM (maybe even FEA) workflows, I definitely would like to see this appear as not only an option, but also as a secondary browser, just like Solidworks.... urggh, I feel dirty. 😉
