I only just found this very cool little feature, being that when you associate something into a template that references another file, it then also shows that template/s as a tab to quickly see / modify associated data.
It just keeps getting better and better the more I play with this software.
I noticed that, too--it's nice because I don't have to open a whole bunch of tabs in my browser and switch between them to look at things!! I also like that it has a dot to indicate whether or not you've edited it since your last save.
