Hello,
is it possible to force OctoPrint to reload the jinja2 tempates without restarting OctoPrint during plugin development? It's a bit of a hassle to do this every time a make changes. The CSS is updated fine after reloading the web frontend. Thank you 
Which version are you developing against? I remember fixing a bug there that prevented hot reloading of Jinja2 templates from working, I think I only fixed it on 1.7.0 (so the current RCs).
I was using the latest stable release (1.6.1). Switched to the current release candidate and reloading the templates is working. Thanks!
