please put me on Cc in replies, as I don't receive mails from the list, thanks!
Almost all my plugins, brushes, etc are in my home folder. How would
it be then?
The article only mention system installed stuff.
it should work by (sym)linking or copying the plug-in files in your
"$HOME/.gimp-2.8/plug-ins" to "$HOME/.config/GIMP/2.9/plug-ins".
