What is the problem?
I would like to add some custom icons to Octoprint. I'm not sure if the system and plugins share the same set of icons but in certain plug-ins (like "UI Customizer") they allow me to choose an icon for something like a control button. I want to add an icons that looks like an enclosure+thermometer, enclosure+fan, etc.
Is there a folder that I can drop new icons in? If so can I access it through Octoprint?
What did you already try to solve it?
I can't see anything special when I take the octoprint SD card out and pop it into my computer.
Have you tried running in safe mode and if so did it solve the issue?
