I want to archieve a update save solution to display only the custom made templates.
No additional addons installed.
I didn’t found a hook, which I could use to remove the unused themes from the output.
I know I could delete the unnecessary themes, but after an update I have to delete the folders again and again.
So I hope someone has a better solution o that I can filter the output.
I have actually used a quick and dirty solution.
I removed all rights from the dirs of the included themes, so that they couldn’t be read.
But this isn’t the best pratices but I want our client could only use the custom theme we have created for him.
