Is there away. Short of restarting the whole module to reload the icon SVG files at \Ignition\data\modules\com.inductiveautomation.perspective\icons?
After modifying and saving them.
I create another svg files for my icon and it doesn’t require any restart only refreshing broswer. User your file name instead of material/icon name.
Create a new file is much safer on ignoring update.
That’s what I do. Especially when testing. I have so many tho! lol
