[Qgis-developer] How to store a QIcon in QGIS project file?

[Germán Carrillo]

It's a visual guidance to navigate your layer tree. It could help you
differentiate, for example, between data authorities (see an example at
[1]). Additionally, as some user stated in GIS.SE, plugin authors would be
able to differentiate groups created by their plugins from other groups.

I by no means think it's indispensable, but would consider it nice to have.

Regards,

Germán
