I'm sure that this method I'm using for a few years now was worked out using information from here gimp-forum.net over several different posts anyway,
this method works also
I keep my main stockpile of fonts in an Ext HD along with folders for brushes gradients and tutorials hints well everything that goes with or can go into Gimp,
the fonts go [copied only] into > /home/YOURNAME/.config/GIMP/2.10/fonts/
Add a Tag for a group or individual fonts, as you add them tag em,
the bottom box is where you can add tags.
Have the name of tags highlighted in top box
The system fonts are a no show until needed if needed
Wasn't able to add the image
