Why not create shortcuts/shell scripts to open a project, similar to the script to create a new post?
I could make it so that if I want to open a project, I cd into the directory belonging to the project, activate the environment and start up a server. I could even make it so that all projects start a server on their own port, so multiple projects could have a simultaneously running server.
So typing $ bredeschool
would cd into the directory /home/wijnandb/sites/heroku/bredeschool
$ cd /home/wijnandb/sites/heroku/bredeschool
Then activate the enviromnent by running
$ pipenv shell
and finally spin up a server by running
$ python manage.py runserver localhost:8000
