Font manager not managing them.

[Krikor]

I've been using the Ofnuts plugin addonCollectionManager for at least 3 or more years.

But having to manually disable the fonts added by the addon every session is a bit annoying.
Another annoyance is that when deactivating a font via the Addon it is automatically removed from any group of fonts to which I have added it in GIMP.

For example, if I use the Addon to load (Activate) the Tangerine.ttf font and add it to the Ex1 group, where I can find it via the use of the filter in GIMP fonts.
When I deactivate this font (which will have to be manually and GIMP needs to be restarted) I will have to remember to add it to this group (Ex1) in the filter again in the future, as it will have been removed when deactivated.

This complicates font management in GIMP. But the truth is that I haven't found anything better.
