I am constantly moving layers in and out of my projects, I was able to set default style for layers and they all the layers I drag and drop to my project get the same style by default.
Lately I have discovered that I can create rule based symbology as a layer style which allows me to hide unselected features while I'm working on a selected feature.
I am wondering if it's possible to save rule based symbology as default for imported vector layers? When I use save symbol as default it saves a QGIS configuration file next to me shapefile but that's good for only one layer, as soon as I change the project I need to set everything up from scratch again by going to rule based symbology, create two rules, fill them in with the expression etc.
