I have selected Jinja2 as my python template language but I don't see Jinja2 as an option under "Settings - Code Style". This seems to be a regression from v2.x. I realize I may be missing some key setting that enables Jinja2 styling but it really shouldn't be that tricky.
My preference would be to have the flexibility to set the code styles for any supported template language whether or not they are currently active in a project.
