Role selection in the browser window #129
Description
Hello, I run 6 printers here via 3 Raspi's with 2 instances of Octoprint each. I have installed the Filament Manager on all instances with access to a central database. In the browser I have 6 windows for the individual printers. What annoys me, however, is that when I want to start printing for a printer, Octoprint always gives me the ink roll of the last print started. I suspect that the role selection is recorded in the cookie. It would make more sense to generate a cookie for each instance, at least for the Filament Manager.
