Sadly I’m not familiar with SVG-graphics and have my Problems with github too.
But maybe it helps someone is more familiar with that if there are further examples for interesting “new” icons to add in the default iconset.
Some examples (I did only in png, sorry): (EDIT: Comments)
Blinds manual mode
Blinds sun depends
For enocean Stick (if allowed to use outside private)
if inactive / unused
Harddisk Stack / NAS
Update 05.04.2021: Some more new Icons.
I really didn’t find the right place in github the icons are stored, so not able to add directly to iconset:
Icons for new “openweathermap” Channels about Air Quality:
Thanks all active developers for their great work!!!
