PyCharm & VirtualEnvs - How To Remove Legacy
When virtual env is enabled, there will be a 'V' symbol active in the bottom part of pycharm in the same line with terminal and TODO. When you click on the 'V' , the first one will be enabled with a tick mark. Just click on it again. Then it will get disabled. As simple as that.
How do I remove all traces of legacy projects from PyCharm?
Background: I upgraded from PyCharm Community Edition to PyCharm Pro Edition today.
Reason was so I could work on Django projects, and in particular, a fledgling legacy project called 'deals'. 
I deleted the legacy project folders.
I then opened the Pro Edition and went through the steps of creating a Django project called 'deals' with  a python3.4 interpreter in a virtualenv.
It didn't work, I got an error message saying something about a missing file, and in the PyCharm project explorer, all I could see was

deals
.ideas 

So I deleted it (ie. deleted the folders in both ~/.virtualenvs/deals and ~/Projects/deals).
I tried again, although this time I got an interpreter with a number suffix, ie. python3.4 (1). 
I continued, and got the same empty file structure.
I deleted both folders again, went and cleaned out the intepreters in Settings > Project Interpreters .
I then tried again, getting 'new' interpreters,until I finally had python3.4 (5) 
Plus, along the way I also invalidated the caches and restarted.
(ie. File > Invalidate Caches/Restart)
Then to prove if it works at all, I tried a brand new name 'junk'.
This time it worked fine, and I could see the Django folders in the PyCharm explorer. Great.
But I really want to work on a project called 'deals'.
So I deleted all the 'deal's folders again, and tried to create a deals Django project again.
Same result.
After googling, I went to the Settings > Project Structure > + Content Root, and pointed it to the folder at ~/.virtual/deals.
Ok, so now I could see the files in the virtual env, but there's no Django files, and plus, the project folder was separate to the virtualenv folder, eg

deals

deals (~/project/deals)       <- separate
deals (~/.virtualenvs/deals) <- separate

deals
init.py
settings.py
urls.py
wsgi.py

manage.py


Really stuck now.
Any advice on how to get this working please?
Eg. how do I
(i) get it back to 'cleanskin' so that I can start up a Django project and get the proper folders in the project space.
(ii) get it working with virtualenv, and ensure that the interpreter doesn't have a number suffix, such as python3.4(6)  
Many thanks in advance,
Chris
