I was expecting that each user could have their own temp folder for the namespace, but it looks like I have missed something in the configuration. User B can see my path and SSH Private Key file as well as work off my branch when he should work off his own branch (when I switch branch his branch got switched too because points to that universal folder)

Looks like the Temp folder for this namespace is a universal location which will not work for multiple users' remote collaboration. In the Studio, each of the developers has a remote git folder from where is working. I thought this extension would allow a similar configuration.
