The browsers of Rapture and Dimension Pro show the total size of all of the sample files in parentheses, for 1MB or more. For example, "Guitar_Bo (29 MB)".
 
Rapture Pro doesn't have that. And it just has the rotating circle as the only indication when it's loading.  It would be nice to have something that shows the loading progress, like a % counter or an increasing bar graph.  
 
But at a minimum the sample size along with the patch name is a very useful things to have.
 
Thanks,

I agree.  Displaying the size after the load is complete seems a bit late

Yes, it is absolutely necessary. It is awful when I browse patches and some patch is loading 15s and after that you realize that it is 2,5gb. It is workflow killing. In addition I'd prefer big patches to be in the separate place. This patches are almost useless for me without Direct From Disk.
