Why is selecting a new virtualenv such an arduous process?

Have you tried enabling a new virtualenv in your Pycharm project lately?  It's pretty terrible.  The dialog to select the interpreter takes a very long time to load everything in /usr/bin, and when it finishes loading, it wipes out the part of ~/.virtualenvs you started to type in because that takes a lot less time than clicking through your entire hard drive.  I feel like it should at least default it to ~/virtualenvs instead of /usr/bin/python.
