Youre right - feel free to make and share a better Version. I think the community appreciates forks and contributions :)

I mean there is a a graph about active users over the last months, so I would argue it does regarding user activity?

its the icon for a LED stripe. I use it to toggle the Hyperion Ambient Light system (its synced with the HDMI input of the projector)

Thanks I used the "ironing" option in the slicer :)
