Ok, I fixed one way. I can now start Gimp out of Rawtherapee. I uninstalled the snap and instead used the ppa. But, I can’t find the plugin in Gimp to open raws with rawtherapee. Any experiences how to manage this if I use an AppImage of RawTherapee? I already made an symbolic link to the AppImage in one of the bin folders where $PATH points, because the wiki said it should work afterwards. But it doesn’t. Andy ideas? I hope I could explain the issue right. I have the feeling that it’s a bit confusing. So let me know if you need more infos. Thanks in advance.
