"Undo" is a very good thing.

I am rather annoyed that they still haven't addressed basic file management, that most Windows software has had since dinosaurs roamed the earth. 

Adding runtimes is sooo tedius.  It defaults to My Computer.  DAZ|Studio lets you add all the runtimes in a folder with a click, but with Poser, you must add each one manually.   Each time, navigating from My Computer to wherever you have the runtimes.  And once again, they are arranged in the order you add them, not alphabetically.  If you use a lot of runtimes, as I do, this is a real pain. 

It's a small thing, but sheesh, it would be so easy to fix, and it would make life a heck of a lot easier.
